Oh so 8chan indeed moderates but not enough? Whats enough moderation by your standard and why should we go with that and not a more lenient one? So we should not only censor direct threats of violence we should also censor allegedly 'celebratory' posts that don't include a threat at all? Do you have any scientific proof that simply 'celebratory' posts cause violence too? Or are we just removing them because they're disgusting? You are aware that bad actors can and probably have come to stir up shit on 8chan to take it down right? Are you going to shut down a whole site because of these few people and they don't have the resources for all the whizbang algorithms that big sites like twitter uses to quickly remove posts but leave up tons of violent leftwing posts nobody care about?

PS 8chan for the most part is hardly edgey. There are a few eccentric groups in the subboards like all communities but in away its actually more like how the old internet used to be before, everything right of communism was 'far right'.
