The Safety Mode functionality allows users to temporarily block out accounts for seven days for using potentially harmful language — such as insults or hateful remarks — or sending repetitive and uninvited replies or mentions. If a user receives a harmful reply, Twitter will suggest that they turn on Safety Mode. Additionally, users will be able to see and undo those tweets and accounts that might have been incorrectly autoblocked by Twitter at any point of time. Those whose account has been included in the beta can test Twitter’s Safety Mode feature via Settings > Privacy > Safety. Previously, this feature was available only to a small feedback group prioritizing people from marginalized communities and female journalists, but it will now be available to about 50% of (randomly selected) Twitter users from the U.S., UK, Canada, Australia, Ireland, and New Zealand.
— Twitter Safety (@TwitterSafety) February 15, 2022 For those unaware, in September 2021, Twitter had announced that it has started beta testing the Safety Mode feature to reduce unwelcome tweets and noise that can get in the way of conversations on the platform. It aims to reduce disruptive interactions. It is currently unclear when the microblogging platform plans to roll out the feature around the world.
