Inevitability, it becomes an I-don’t-like-opinions-other-than-my-own button:
Unfortunately, some of the negative effects of a report abuse button that people have feared seem already to have happened. Shortly after the function became available on certain smartphone apps, accounts like @transphobes – which retweets the kinds of violent threats and hate trans women and men get online, to raise awareness of bigotry against them – was suspended.
Whether it was targeted by a concerted campaign of opponents or automatically suspended without being reviewed by Twitter is unclear. It certainly raises the question: how easy is it to mistake awareness-raising for bigotry? And what does it say when Twitter bans an account for retweeting things it otherwise is not acting to stop?
