A classic CureZone 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.
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. Very few trolls come to CureZone out of pure skepticism.
Finally, trolls create a paranoid environment, such that a casual criticism by a new arrival can elicit a ferocious and inappropriate backlash.
When trolls are ignored they step up their attacks, desperately seeking the attention they crave. Their messages become more and more foul, and they post ever more of them.
Alternatively, they may protest that their right to free speech is being curtailed.
Perhaps the most difficult challenge for a webmaster is deciding whether to take steps against a troll that a few people find entertaining. Some trolls do have a creative spark and have chosen to squander it on being disruptive. There is a certain perverse pleasure in watching some of them. Ultimately, though, the webmaster has to decide if the troll actually cares about putting on a good show for the regular participants, or is simply playing to an audience of one -- himself.
