I agree, bashers come in several flavors. There are the ones described in that post (we can all think of some lone wolf bashers who are like that), but there are also the crazed BoobyKirk flavor.

I do agree with the "posting under several aliases" for sure. There was one hilarious one on the NNVC board years ago where "two" people kept starting their posts with "as usual xxxx" is right. One time he got confused which name he posted under, and replied to his own post "as usual xxxx was right." Oddly enough seconds after I pointed that out, both of his posts and my post were deleted. Obviously a moderator in action.
