Calling someone a troll gets you banned!

So, if I said: Darth= troll I would be trolling?

Its not trolling if its true!!!!!! 

I think it is considering an insult if I called darth a troll, now if it pissed of someone that loved darth, I might be trolling a person.

Now if I expected it to piss off someone, and I did it for that reason, it might be considered flame baiting and/or trolling.
