Among the top 10 protest movements on Twitter last year, half of all related posts were generated by less than 10% of the users involved in the campaigns, according to an analysis by The Yomiuri Shimbun.
Such campaigns have spread rapidly since the outbreak of the coronavirus pandemic and claims made by a small portion of users have been amplified, according to the analysis.
Calls to post tweets with a particular hashtag at a certain time and date have triggered online protest movements, with some campaigns appearing on Twitter's list of trending topics on the platform and elsewhere.
