Trolls spend a lot of time online

I am new at this part of the forum as part of Angry Bear. Please let me know if I have the basics correct. Knowing how much time posting takes, I am amazed at the quantity of time necessary to troll.

1. A classic troll is trying to make us believe that he is a genuine skeptic with no hidden agenda. He is divisive and argumentative with need-to-be-right attitude, “searching for the truth”, flaming discussion, and sometimes insulting people or provoking people to insult him. Troll is usually an expert in reusing the same words of its opponents and in turning it against them.

2. While sometimes, he may sound like a stupid, uninformed, ignorant poster, do not be deceived! Most trolls are highly intelligent people trying to hide behind a mask of stupidity and/or ignorance! They usually have an agenda.

3. Trolls are utterly impervious to criticism (constructive or otherwise). You cannot negotiate with them; you cannot cause them to feel shame or compassion; you cannot reason with them. They cannot be made to feel remorse. For some reason, trolls do not feel they are bound by the rules of courtesy or social responsibility.

4. When trolls are ignored they step up their attacks, desperately seeking the attention they crave. Their messages become obnoxious, and they post ever more of them. Alternatively, they may protest that their right to free speech is being curtailed.

5. When a troll attacks a message board, he generally posts a lot of messages. Even if his messages are not particularly inflammatory, they can be so numerous that they drown out the regular conversations (this is known as ‘flooding’). Needless to say, no one person’s opinions can be allowed to monopolize a channel.

6. Trolling is a form of harassment that can take over a discussion. Well meaning defenders can create chaos by responding to trolls. The best response is to ignore it.(?)The ultimate response to the ‘free speech’ argument is this: while we may have the right to say more or less whatever we want, we do not have the right to say it wherever we want.

Then the question becomes how to deal with a troll who is trolling under our bridge.
