Earlier quoted context omitted.
There is the popular belief that shunning people or groups of people like this will lead to their exclusion from society, not yours.
If you can’t shun someone for their direct misbehavior, then why can you decide not to mute someone? Note that I never told you that you’re not allowed to talk to them. I just said they’re not allowed to harass me or my users anymore. You can still hang out with them all you like.
I guess your users were okay with you setting blocks?
