Are you muting or blocking them? I only recently actually looked at the difference.
Some people's posts I don't want to see and others I don't want them to see mine, but if I am just not interested in their content I mute them, maybe they still like my content and share it with their followers. The problem is that you, however, then still attract them to your posts, so blocking is the best.
@Stark9837 They're blocked. I don't want to give them write access to my future posts.
