Agree in part. I have an issue with posters saying ‘You are a troll’ on public forums unless it is blatantly true. And maybe that is where the ‘grey area’ is. But I wouldn’t have a problem with someone asking politely ‘Are you a troll because it seems ....’. Then again I can see how a troll might even then play games with that approach. I do think posters should ‘ignore’ trolls if they find them offensive, suspect they have several user names, are rude and/or are out to wind other posters up. They do seem to present in many public forums other than these too. My understanding is that they crave attention because they have none in their own lives.
