i disagree with therealjcdenton but you're missing the point.
they're saying that 196 "infected" the previously good other communities on Lemmy, so them blocking 196 itself doesn't do much, and they're losing out on content if they block the"infected" communities as well.
This is a natural downside of the fediverse. I'm sure there are hexbear folks who just made a new account somewhere and are in all our feeds again. Nothing to do about that
Reddit and similar had the same issue but in general account hopping was less normal
I didn't even know 196 was a thing on Reddit but I blocked them on Lemmy because my main page was all spam from them. None of it was funny to me, or entertaining at all. It's the only community I have blocked too.
