Twitter is currently testing a feature that allows you to remove followers without notifying people. The platform wants to introduce a new set of privacy settings.
If users want a follower to unfollow them, they should stop blocking that person. Through a new function, Twitter wants to make it possible to remove a follower without them realizing it.
The platform aims to give people more control over who can see their posts and likes. There would also be a function where old tweets are made invisible to other users after a certain time.
The feature that allows you to remove followers is in a testing phase. It is not yet clear whether this feature will effectively be rolled out to the general public.
