I’m not blaming just the lockdown but it certainly played a part. For a lot of people who are now legal adults it happened at a formative stage of their social development.
“I wouldn’t just put the magnifying glass on 4chan when Reddit and Kiwi Farms are just as bad if not worse.”
True.
Maybe uncharitably, my first thought when reading a post like this is “what shitty thing do you want to say?”.
But I don’t know you so maybe I am being uncharitable.
But you have to realise the fediverse in general is not owned by capitalist orgs with high priced legal teams. Its mostly small teams of private individuals. If someone posts something illegal, including defamatory, in their legal jurisdiction (which is probably not the USA) then they might be on the hook for it too.
Even if you run your own instance if you’re enough of a dick it’ll get defederated or you’ll be banned from multiple instances/communities.
Learn to play nice in other peoples yard. Its hard sometimes but just walking away and blocking is the best option. Sometimes I need to make more effort to do that too.
