Naa I don't. I get enough laughs from my irl friends, I don't need to go around on this website making dumb jokes/acting stupid/trying to piss people off for giggles. It has always pissed me off when I've asked a serious question, and some troll will give a dumb response, so I tend to just take everything seriously on this site and try to help people. If someone does troll me though, I'll either respond with trolling which usually confuses them or pisses them off, or just ignore them.
(1.) Yes I troll, usually by being sarcastic or just being an asshole. (2.) Depends. Sometimes I won't a whole day, sometiens it will be 5 times a day. (3.) I only go anon if I'm REALLY about to say some f**ked up sh*t.
