An anonymous reader quotes a report from BuzzFeed: In 2015, then-Twitter CEO Dick Costolo secretly ordered employees to filter out abusive and hateful replies to President Barack Obama during a question and answer session, sources tell BuzzFeed News. According to a former senior Twitter employee, Costolo ordered employees to deploy an algorithm (which was built in-house by feeding it thousands of examples of abuse and harassing tweets) that would filter out abusive language directed at Obama. Another source said the media partnerships team also manually censored tweets, noting that Twitter’s public quality-filtering algorithms were inconsistent. Two sources told BuzzFeed News that this decision was kept from senior company employees for fear they would object to the decision.

A different source alleges that Twitter did the same thing during a question and answer with Caitlyn Jenner.
