A problem I’ve seen also is creating a niche community because you don’t want to just get the general content, but since there’s simple fewer users it’s just dead. And when someone else thinks about switching to Lemmy, they see a bunch of dead communities and are like “oh this site is dead.”

It’s annoying but on a newer site(/federation of sites) those niche communities need to be conversations that start in a more generalized community that enough people want to branch it off into it’s own thing. So there’s already core users, so it’s not DOA.

Unless they get banned

The problem with that is that any product that was good three years ago is far from guaranteed to be good now. Everything is getting shittier and less consistent. Any given product run manufactured in a different factory than the last run if there’s a lower bidder. I don’t trust reviews older than like six months at this point.
