Hashtag activism refers to the use of social media hashtags for Internet activism.^[1] The hashtag has become one of the many ways that social media contributes to civic engagement and social movements.^[2] The use of the hashtag on social media provides users with an opportunity to share information and opinions about social issues in a way that others (followers) can interact and engage as part of a larger conversation with the potential to create change.^[3] The hashtag itself consists of a word or phrase that is connected to a social or political issue, and fosters a place where discourse can occur.^[4] Social media provides an important platform for historically marginalized populations. Through the use of hashtags these groups are able to communicate, mobilize, and advocate for issues less visible to the mainstream.^[5]

Supporters of the power of hashtag activism believe that it allows users to connect with individuals from all over the world and share information quickly. Critics, on the other hand, doubt that hashtag activism leads to real change, as users are simply indicating that they care enough to post a hashtag, rather than taking practical action to make a difference.^[6][1]

The hashtag, as it is currently used across social media sites was first proposed on Twitter by former Google developer Chris Messina, in 2007. The purpose of the invention was to create a meta tag that allowed users to track dynamic content in relation to a particular event or topic. Twitter's initial response to the use of the hashtag for such purposes was negative. The social media site posted that "these things were for nerds"^[7] but later that year saw the impact with use of the #sandiegofire which allowed users to track content related to the fire, the safety of loved ones, and general updates. The use of the hashtag has now spread to other social media sites including Facebook, Instagram, and TikTok.^[2] Since 2007, the hashtag has been used to coordinate conversations online, find supporters, and arrange protests allowing for users to be active participate in social and political movements.^{[citation needed]}

While "fake news" or politically motivated disinformation (PMD) is not a new occurrence, the sentiment and spread of distrust of news coverage has become more notable since the 2016 U.S. elections cycle. The hashtag, #FakeNews, gained major popularity in 2016 when Donald Trump claimed that the negative press coverage he received was due to the spread of false stories. Since the emergence of this hashtag, there has been an increase in policy-related bills and laws regarding the proliferation of inaccurate information globally, which further politicized the issue and raised concerns of impending censorship. The emergence of social media has allowed for "fake news" to spread much quicker than regular news and information, pushing technology companies to take a more active role in detecting and removing "fake news".

The terrorists were planning to enter the stadium along with other people.^[127] Despite the person being prevented from entering, it demonstrated the severity of how people are risking their own lives, indirectly affecting others. Following the incident, more than 70 million people began to share this news on various social media platforms in order to reach a broader audience.^[128] For example, Facebook enabled users to change their profile picture to a transparent overlay of the French flag to indicate support to the victims. Twitter was also utilized. However, rather than creating a transparent overlay on a Twitter's user profile, a hashtag was created to emphasize support.

Flygskam is a Swedish word that literally translates as "flight shame". It is the name of an anti-flying movement that originated in Sweden last year, which encourages people to stop taking flights to lower carbon emissions. The idea was originally championed by Olympic athlete Bjorn Ferry and gained momentum after teenage activist Greta Thunberg's mother, the opera singer Malena Ernman, publicly announced she would stop flying, with various Swedish celebrities following suit. Thunberg herself traveled largely by train during her recent two-week tour of Europe.^[130] The activism has seen real results in Sweden as the sales of airline ticket sales declined by 4% in January 2020 due to the increasing public awareness to the carbon footprint resulted by commercial flights.^[131]

Prior to 2020 #humanizethebadge was primarily circulating on Twitter and Facebook by organizations promoting stronger bonds between law enforcement and the communities they serve, such as the nonprofit group Humanizing the Badge.^[136] This need for betterment was due to police brutality killing George Floyd on May 5, 2020. This ignited the public's want for change and placed the Black Lives Matter protests at the forefront of the media.^[137] Behind the protest lines, the hashtag humanizing the badge popularized. The purpose of #humanizethebadge was for officers and officers' loved ones, to show their communities the person behind the police uniform. #humanizethebadge is mostly seen on TikTok with over 2 billion posts including the hashtag. These posts strive to humanize officers to reveal them as more relatable and trustworthy.^[138] This relatability is an attempt to bring them closer to the citizens and communities they serve.^[139] Through the use of TikTok officers are able to reach a wider audience. TikTok allows creators to jump from audience to audience and trend to trend.^[140] These videos receive tens of millions of views promoting bureaucratic propaganda due to officers' supporting the appearance of institutional legitimacy.^[141] Within the videos they are able to promote themselves as your average, relatable human, while being in uniform, thus associating themselves with the police department. Creating this link humanizes law enforcement as a whole, in an attempt to show police as the 'good guy'.

However, this hashtag is not universally promoted by police officers. A former police officer and current entrepreneur Autumn Clifford believe being a police officer is a great responsibility that needs to be represented by leaders. She notes historically society has never loved law enforcement, and citizens do not like being told what to do. Thus they need leaders to guide them in a positive direction. Civilians need to see police as leaders within their own communities. Clifford suggests this can be achieved by officers having real and honest conversations with civilians, and by going out of their way to relate to citizens. This can lead to a greater respect for law enforcement. She provides an example of being called to a troubled teen's group home and ending the encounter with a dance battle. This encounter changed the teen's perspective on her, and referred to her as the 'cool cop' for the rest of her time on the job. This one simple interaction humanized her to the group of teens.^[142]

The hashtag #NotOneMore developed shortly after the May 23, 2014, shooting in Isla Vista, Santa Barbara, California. During this incident, six students attending the University of California, Santa Barbara, lost their lives.

The phrase became a hashtag on social media afterwards. Richard also worked with Everytown's digital team to create a tool to allow participants to send postcards to their senators, congressional representatives, and governor containing the phrase "Not One More".

The March for Our Lives protest began after the Marjory Stoneman Douglas High School shooting in Parkland, Florida on February 14, 2018.^[144] In response to a surge of gun violence in schools and the 17 dead after the Parkland shooting, people began to rally around the hashtag #neveragain. The hashtag, indicative of the larger movement against gun violence, spread across social networks and went viral in early 2018.

Additionally, the movement organized walkouts in remembrance of the lives lost due to gun violence. In March 2018, hundreds of marches were organized across the country in support of stricter gun laws, many of which were met with resistance from anti-protesters.^[144] Since February 2018 there have been 123 laws passed nationwide at the state-level to address concerns of gun control.^[145]

The "challenged" individual then either has to respond by dumping ice water on their head, or donate money to a Motor neuron disease or amyotrophic lateral sclerosis (ALS, also referred to as Lou Gehrig's disease) charity. However, doing both is also an option. The encouragement of the challenge is to circulate the video or photo on social media websites and applications with their community, friends, and family to show their support in raising awareness of ALS/MND.^[198] The involvement of #icebucketchallenge with the global audience of social media generated so much awareness and support that in early August 2014, the national ALS charity foundation president Barbara Newhouse, directly attributed the movement to a fundraising "surge" of $168,000 that accumulated in just a week. That figure contrasted with the $14,000 raised in the same time the year prior prompted the CEO and her 38 years in the industry to view the difference in support as "crazy".^[199] A month after the August 2014 fundraising week the number of videos that were directly associated with the #icebucketchallenge was tallied on the Facebook website from June 1 to September 1 at 17 million, according to the Facebook Newsroom.^[200] As the videos continued to climb, so did the challenges. Eventually, public figures such as James Franco, Charlie Rose, and even former president George W. Bush took an activist role in raising money for research and awareness of the ALS disease.^[201]

The Hallyu Wave, which literally translates to "flow of Korea" (or more commonly known as the Korean Wave) represents the social movement in connection to South Korean culture and entertainment. Economically, Hallyu is tremendously profitable, attracting millions of tourists and fans per year and produces many forms of entertainment, such as Korean pop music and television drama series, ultimately generating billions of US dollars in annual revenue which further strengthens its economic prosperity and stability.^[202] Furthermore, being a powerful social movement in its own right, Hallyu holds considerable influence in politics as well. The ninth president of South Korea, Roh Moo-hyun, once stated that Hallyu can be used to improve or repair the tense relations between the Koreas.^[203] Still, North Korea does not have its own rendition of Hallyu and even rejects it; for example, when Psy's "Gangnam Style" was released in 2012, North Korea viewed the song with contempt because while South Korea was attracting positive attention, it was also undermining the impoverished conditions of North Korea at the same time.^[204]

In 2014, protests of the then-recently enacted anti-gay laws included targeting the corporate sponsors for the 2014 Winter Olympics in Sochi Russia. Among the sponsors was McDonald's, whose marketing included the hashtag #CheersToSochi, which was hijacked by the queer activist group Queer Nation.^{[205][206][207]}

In June 2015, The United States Supreme Court ruled in favor of same-sex marriage nationwide.^[208] This led to the creation of the hashtag #lovewins.^[209] This hashtag earned over 4.5 billion impressions on Twitter. President Barack Obama joined in and tweeted using the hashtag.

Started by Janet Mock in 2012. This hashtag was used to support Jenna Talackova during the Miss Universe pageant.^[210]

This hashtag is used to showcase authors from marginalized or underrepresented groups who write characters from those same groups of people. This hashtag represents stories being told by people who have lived those experiences.^[211]

Hashtag activism has been referred to by critics as a form of slacktivism. Slacktivism is using social media as a vehicle to provide minimal support for a political or social issue. Hashtags, likes, shares, and re-posts are all seen by critics as superficial support that provide minimal change and require little effort.^[212] The ease of hashtag activism has led to concerns that it might lead to overuse and public fatigue. Critics worry that hashtag activism allows participants to be satisfied with a public symbol of concern, rather than taking action.^[1] The passive nature of the practice can lack the passion once displayed in movements from earlier eras.^[3]

Other critiques of hashtag activism stem from the belief that online social movements are often started by privileged individuals, rather than by those who are most affected by the cause itself.

Notable critics of hashtag activism include former Alaska governor Sarah Palin, Canadian journalist Malcolm Gladwell, and Nigerian American writer Teju Cole, who all have argued that hashtag activism encourages lazy, ineffective participation that does not elicit any change.^{[213][214][215]}

While critics worry that hashtag activism results in a lack of true action offline, supporters believe it to be an easy and effective way for users to share their opinions, find information, and provide moral support to issues.^[216] The hashtag allows users to interact with one another to mobilize efforts without supporters needing to be in the same physical location or the same time of day. As posting a hashtag or reading posts linked to the hashtag requires little effort, more people are able to participate. This can build awareness by connecting it to personal stories, experiences, emotions and thoughts.^[217] Identifying shared experiences builds rhetorical connections between people who would never otherwise meet, enabling users of hashtags such as #MeToo and #BlackLivesMatter to support and validate each other and helps to expand and enrich awareness by providing access to multiple narratives.^[217]

Supporters such as Bev Goodman, who initiated the #WhyIStayed movement about domestic violence, believe that hashtag activism can begin a chain of events that can lead to sustained engagement and political action.^[218] For instance, in 2012 when the Susan G. Komen for the Cure foundation decided to stop funding mammograms through Planned Parenthood, social media users tweeted, #standwithpp, and #singon; later that same week, Komen reversed its decision.^[3] Planned Parenthood clinics do not perform any mammograms, but they make referrals for patients.^[219][220] Social media fosters a fast-paced environment that allows organizations to quickly see how individuals react to policies and decisions, which in turn creates the opportunity for those responses to be taken into account if the organization is open to changing the policy or decision.
