You mean that you feel pleasure by being evil?
Idk...
Try following
@SkinnyJungkook method (in other places of the internet, of course).
-Make threads asking weird questions about pretty girls from dramas, so people will see you as a potential stalker
-Put some polemics here and there, acting like a religious fanatic. And when people says that they doubt your faith, you act like they are insulting you. Then you pretend you are angry with them.
-Make threads asking how to use certain forum features, and say it is all too confusing for the average user. Shame on the tech team, tsk tsk.
-Also be a pervert. Embarrass the other people by saying sexual things about their idols, if you can apply the polemics part here, even better.
-Harass and tease the admins.
I think those are the basics.
