Nah, some people just dont like being insulted, even if it is by people they have never met. I have been on this forum for quite awhile now, and I want to stay her for even longer. I wouldnt want a bad flame or something to haunt me.
Besides, alot of people arent very good at insulting people. Me, in real life, I am the nicest person that I will probably ever know. Every now and then I can come up with an accidental burn or something to get somebody, but I am very passive, and only passive-aggressive when riled.
