This is all terrible.
If I go on Mastodon am I supposed to check that the author of each toot hasn't done any crimes somehow before I click the little boost button? How would one actually go about doing that?
If you actually know someone has done or continues to do bad things that ought to get them ejected from the space, are you supposed to respond to that by refusing to interact with them while they are in the space, when they are not doing the bad things, as a sort of poorly coordinated attempt to eject them?
If we have a list of people so terrible that being nice to them means we should exclude you, then why the hell are they still here?
