What is the clinical definition of trolling on Fluther?

More than a few times over the last month, when the discussion of suspensions, banning, and sometimes other issues are had, trolling keeps popping up. In reality, one person’s trolling is another person’s real and honest question. If it is something asked that someone really believes as attested to by their details, just because other Flutheronians don’t like it, or a mod or mods, it gets nixed as trolling? Is it the in-your-face way a question is asked that makes it trolling; because it wasn’t sugarcoated? Does a particular subject make it automatically trolling? Can you quantify trolling as these words, those subjects, that issue, handled that way, etc? It just seems that trolling is too nebulous.
