Can the trolls be stopped?
In all cases trolls should be ignored. If a troll is really determined to post messages in AWW, there’s always a way to do so, either through shell accounts, friendly news servers, remailers, etc. The best thing to do is ignore them, because that denies them the thing they want the most — recognition. Arguing with them is the worst thing to do, because their only real interest is in provoking a response.
