Online firestorm

An online firestorm is a rapid surge of negative word-of-mouth and public complaints directed at a person, company, brand, politician, or institution through social media platforms. Online firestorms typically develop within hours and spread quickly across social networks. They can damage reputations, prompt customer or audience defections, and have contributed to the resignation of public figures. Only a small fraction of negative social media posts attract enough support to become a firestorm.

The term was introduced in 2014 in marketing communications literature by Pfeffer, Zorbach, and Carley, an interdisciplinary team who chose "firestorm" to reflect the intensity of the aggression involved and argued that the way social media networks are built makes firestorms a distinct phenomenon rather than just a faster version of traditional negative word-of-mouth. Online firestorms have been studied both in commercial brand communities, where they target businesses, and in social and political settings, where they target public figures, institutions, policies, or perceived violations of social norms. Researchers approach the topic from marketing, communication studies, political sociology, and information systems.

Related concepts

As a form of mass verbal venting, online firestorms consist of aggressive comments directed at an absent target that escalate as other users add similar comments. In the marketing literature, the individual posts are referred to as negative electronic word of mouth (eWOM). Online firestorms are discussed alongside related forms of aggressive online commenting such as flaming, cyberbullying, and incivility in online discussion forums. The term is also used in mainstream English-language press to describe viral social media controversies.

Characteristics and dynamics

Online firestorms typically develop and fade quickly. In a study of 472,995 negative customer posts on the Facebook pages of 89 S&P 500 companies, 78% of incidents started and ended within a single day, with the final supportive comment posted within 24 hours of the original complaint. This short timeframe distinguishes online firestorms from product-harm crises studied in earlier marketing research. Studies have also found that aggressive commenting is far more common in social media than in face-to-face settings. An analysis of 532,197 comments on 1,612 online petitions found that 20.62% contained at least one aggressive expression, compared with around 4% of bystanders who react aggressively when they witness someone breaking a social rule offline.

Several characteristics have been identified of the post and its sender that predict whether a negative post catches on: the intensity of the negative emotion in the post (anger, fear, and disgust outperform sadness, consistent with broader research on viral content), how well-connected the sender is within the community, and how closely the post matches the community's typical writing style.

In a 2016 study, Rost, Stahel, and Frey describe online firestorms as a form of digital social norm enforcement, in which a digital society calls out public figures and organisations seen as having broken shared social rules. Three conditions make this kind of public criticism much more likely online than offline: posting a hostile comment is cheap, quick, and risk-free; controversial topics and news media scandals offer real personal rewards such as recognition from like-minded readers; and social media reliably connect people with strong personal convictions to the cases they want to call out.

Cyberbullying research has suggested that anonymity drives online aggression by lowering inhibitions, a pattern known as the "online disinhibition effect". Research on firestorms specifically has not borne this out. In one observational study of a German petition platform, only 29.2% of commenters chose to remain anonymous, and those using their real names were more aggressive, not less. A separate laboratory experiment found that anonymity alone had no significant effect on how aggressively people commented; what mattered most was the tone of the surrounding comments, with participants writing more aggressive comments when peer comments on the same page were also aggressive.

Twitter (now X) has been identified as a platform especially conducive to firestorms because of its short message length, real-time format, and rapid information turnover; later research has examined firestorm dynamics on Facebook, Twitter, Weibo, and other platforms. Several widely documented cases, including McDonald's #McDStories campaign, #deleteUber, and the United Airlines passenger removal, played out primarily on Twitter. Firestorms are also amplified by a feedback loop between social media and traditional media: press coverage drives additional online activity, which in turn invites more coverage.

Cultural context also shapes who becomes a target and which issues drive a firestorm. A six-month comparison of trending content on Twitter (United States) and Weibo (China) in 2019 found that American users were more likely to target government and politics and to mobilise collective action against them, while Chinese users were more likely to target corporations and media organisations. American firestorms tended to criticise ability-related failures, such as poor quality, performance, or competence, while Chinese firestorms tended to criticise social-responsibility failures, such as ethical lapses or unfair treatment. The threshold for an event to become a firestorm was also significantly higher on Weibo than on Twitter, with a story needing roughly twenty times more sharing to reach trending status.

Well-documented examples

• Karl-Theodor zu Guttenberg plagiarism affair (2011): online debate over allegations of plagiarism in the doctoral dissertation of the then German federal minister of defence, which led to the revocation of his PhD and his resignation.
• Christian Wulff corruption allegations (2011 to 2012): social media amplification of corruption accusations against the then German federal president, contributing to his resignation; the underlying allegations were later rejected as unfounded.
• McDonald's #McDStories campaign (2012): a Twitter hashtag promoting McDonald's was hijacked within hours by users posting negative experiences and complaints; the company stopped promoting #McDStories two hours after launching it.
• #deleteUber (2017): a Twitter campaign protesting Uber's perceived response to a taxi strike during demonstrations at United States airports, leading to widespread account deletions.
• United Airlines passenger removal (2017): the forcible removal of a passenger from an overbooked flight, captured on video by other passengers and circulated globally within hours.

Corporate and organisational responses

Firm responses to negative comments in brand communities have been described as falling into two main types. Disengaging responses try to shut down the public conversation or move it elsewhere; they include silence, suggesting that the customer switch to a private channel, and offering compensation directly. Engaging responses deal with the complaint in the public thread, either with empathy (sympathy or reassurance) or explanation (reasons for what went wrong).

In one large sample, firms replied at least once to 70% of complaints, with 93% of first replies arriving within an hour. Channel changes and apologies were the most common types; explanations and compensation were comparatively rare. The effectiveness of a response can depend on the emotion in the original post: explanations are better at calming angry or disgusted complaints, while empathy works better on sad or disappointed ones.

Effects

Documented consequences for the targets of online firestorms include damage to reputation, loss of customer goodwill, customer defection, and in some cases measurable drops in sales and share price. Evidence on financial impact is mixed, with firms that hold strong prior reputations often recovering quickly. Online firestorms have also contributed to the resignation of public figures, including Karl-Theodor zu Guttenberg and Christian Wulff in Germany in 2011.
