The sad fact is that most of the time, supposed ‘trolls’ are really just means or idiots. The OP falls into the former category (no offense, we’re all new once).
Labeling every newb/idiot a troll just gives them a scapegoat excuse. I can’t tell you how many times I’ve seen people play poorly in a game and try to claim “I’m just trolling” as an excuse.
Stop being enablers :P
