However, the sad part is that when (This is a bigger example) a community 'blacklists' people they diverse into other communities and essentially 'rot' them out, they become corrupted because all the misfits and deserted people had to leave the healthy place (your brain?)

I simply block all that hurt my mental, brain, etc. Sadly it also hurts a lot of people because they get neglected, but I can't take care of that many people by myself, so hopefully they connect with healthy people too
