Let's be realistic...
some of the things he was saying were
sometimes true...yea, he evidently did some rudimentary research, but...his attitude, more than his information, is what made him a troll.
And he was a troll whether he meant to be or not. He started with calling people idiots straight away. Trolling is more than simply looking for a reaction from people. It's also about causing a disturbance any way necessary.
IMO, this kid tried the first route, by stating that he was getting a 'conda after 2 years with cornsnakes. That didn't get people riled, it only got him information, so he started calling people names. He got away with that 3 or 4 times and STILL didn't get the reaction he wanted...so he started outright cursing. It was definitely a troll-progression thread...
