Trolling is a very ambiguous term...I was kicked off Randi Rhodes board for being a 'troll' or 'flamer', and Im a liberal and they are a liberal board!! The users thought the moderators were crazy, but they banned me anyways...many think a troll is someone who just like to stir things up...that is nt true, as that is just a good poster (oif you dont stir things up, the board is boring)...in fact a flame, or troll is:
"the act of sending someone an outrageously insulting message, whether by private email or in a public
posting, usually because you disagree with something they have said. A good flame mixes a razor sharp wit with a devastating put-down so that the other person will only make themself look silly if they dare disagree -- "The absurdity of your ideas is exceeded only by the incoherence of your remarks, beginning with..." (from http://livinginternet.com/i/ia_nq_send.htm#flame )
So it is more specifically the comments like "If you believe that, you deserve to die" that are flames and trolls, not just giving an opposing opinion from that of the concensus of that particular board.
