Has anyone actually won against Anonymous? I've heard of people taunting them and having their web sites owned and reputations ruined, but never of someone who taunted them and forced them into capitulation.
Granted, it's much harder to quantify a win against Anon, given its distributed nature. Perhaps we could consider any operation removing Anon's ability to disseminate obscenity free, literate, and rather florid public letters as victory? I don't know if they've got one guy doing all of that, but if not, they must have one hell of an in-house style guide.
Anyway, they generally seem to have good policies. Some of it veers toward the juvenile-revenge trap, but by and large, I'll take a victory by them over one by people promoting web blocking, or the outlawing of pretending to have been in the military, or compulsion of people to place anyone else's text next to their own with no government oversight. Anonymous wins -that- one hands down, fart contest or not.
