First off, I'm talking about culpability, not liability. Conflating morality and legality (not to mention censorship and providing a platform) makes your entire post nonsensical. And in the context of culpability, it's obvious that such a relationship only exists when the individual with the power to prevent bad action is aware of the action. So in this case, where Hotwheels is not only a participant in the relevant boards on 8chan but has expressed approval of what's happening, it's easy to hold him culpable (and probably liable as well, for what it's worth).
