I had one like that. He would gladly hijack ANY thread no matter what the topic just to call me out. But he eventually got perma banned.Obviously you havent run into some ahole like i have...HE'S the only 1 on my ignore list....everytime I posted in any thread this jerk would come and point me out and try his best to get me banned...
So you see the moral of the story is just keep giving the Asshole enough rope. Sooner or later they always hang themselves .
