In my defense, I made it clear that I think this is one of those rare cases where Internet-vigilante justice is not only excusable, but possibly even noble. This man is a truly reprehensible human being, and may have found a way to continue to act in this way with impunity. If there is absolutely no recourse available to civil society, I really don't have a problem with him getting the worst Anonymous has to offer - which, let's face it, pales in comparison to what the state can dish out when it wants to.
In their defense, it seems like many of the high-profile, highly organized campaigns by Anonymous have been against worthy targets like drug cartels and cults, rather than some random vile post by some script kiddy on 4chan.
I could very easily see them going after this guy.
