Certainly there were other people involved, and hopefully they will receive their due as well, but to say he's just a "fall guy" is not at all accurate.
I might be late to the party. However, I still want to warn you guys that by shutting down these sites, you are doing nothing more than hiding the filth under the rug. There is an adagio going on 4chan that shutting down /b/ would be similar to clogging a toilet: it WILL overflow somewhere else.
Congratulations, you have shut down yet another site. Do you think these people and their ideologies have disappeared? Nope, they are now gone into an even more remote corner of the internet to foster even more anger.
