Elitism ? definitly. Especially linux. But toxic ? I only saw cordials talks in here, with a few trolls here and there.

As for csam I never saw any scrolling a bit every days. I saw people talking about another instance encouraging it and troll spamming, it but never once saw it myself.

What I saw on reddit without searching was almost daily gore. And definitly sone real csam (this was a long time ago, seems to be fixed now)
