Twitter is testing a new safety feature aimed at reducing unwanted interactions. As explained in a Twitter Safety blog on 1 September 2021, Safety Mode temporarily blocks accounts (Author Accounts) found by Twitter’s artificial intelligence (AI) to be sending harmful or uninvited Tweets to a user (User). Author Accounts may be automatically blocked from interacting with a User who has activated this feature if the messages from those Author Accounts use potentially harmful language (like insults) or send repetitive uninvited replies or mentions, unless the User already follows or frequently interacts with those Author Accounts. Auto-blocked Author Accounts will be unable to follow the User’s account, see their Tweets or send them direct messages for seven days. Users can enable and disable Safety Mode and undo auto-blocks at any time through their account settings.
