We had arguments about this when I was on staff. The word "troll" has a specific definition in terms of the Internet, and under that definition, trolling itself is both intentional and a ToS violation. I argued that honestly calling out intentional trolling behavior should be allowed and should be no more of a violation than calling chillyinCanada a Canadian.
The response usually was that you can call out the behavior without calling someone a name. The example would be that it is OK to say that a statement someone made was idiotic, but it is not OK to say that person is an idiot. I get that. There is a difference. Anyone can make a statement that, in hindsight, turned out to be idiotic. I have some instances in my biography. That does not make that person an idiot. No one participating in these forums is an idiot, and no one intends to make idiotic statements. When it comes to trolling, though, trolling behavior is intentional; the person is intentionally being a troll.
Look up the many sock puppets under which the oft-banned IdocStave has abused ScubaBoard for an example of an out and out troll.
I, for one, do not believe Dody is a troll. Not at all.
