Honestly, that didn't help. There's a wide type of "controversy" there, and I don't see how 4chan are inherent to any of them, they could've been done via any forum. Or maybe I missed something, specificity would be good.
It's a well known forum with a lot of users, to blame the "4chan community" would seem to be either a fallacy of composition or, ironically, of division, depending how the claim is laid out.
I'm also not sure how the site admins would stop them?
