Well, if you're going by the broadest, most inclusive definition, I have committed the crime, but I've also told a lie and don't consider myself a liar.
I've vehemently defended/opposed statements but I don't consider that trolling. I have on rare occasion, however, entered a forum because I was unaware just what the fuck was being discussed, and the posters were having such a heated, passionate discussion about saiyans or something that I just had to pick a little bit. It was all in good fun, and in one instance after I was branded a fucktard fagboy kiddie-fucker or something to that effect, I calmly explained that I actually knew it "isn't fucking Yu-gi-oh!" they were discussing and was just playing around. The other guy actually admitted that he was having hormonal issues having recently entered a new phase in puberty and apologized.
