IMO, dead special interest communities are the cancer consuming the fediverse. Nothing wrong with a small active community, but a small community with a half dozen posts from 3 years ago is a big sign saying “go back to reddit, this place is dead”.

That’s the position we have at !fedigrow@lemmy.zip , still every time we suggest to close a dead community people show up and argue that consolidating communities is turning this place into Reddit.
