There are plenty of examples, Ken, and I only need whisper "dpreview" or our "deejaaa" who now hides behind another pseudonym. And yes, obviously, one begins by reading what's said, but when you see the same trollish contributions and from the same anonymous poster, it's a matter of it walks like a duck, it quacks like a duck....
I used to moderate one forum (Peter Krogh's DAM Book) where we allowed anonymity only by exception and insisted on posters addressing each other by name. The latter was at Peter's insistence, not mine, but I came to think it worked well. Would it be a bad thing here?
