SO much hate in this thread over nothing harmful; it's so sad. Him signing his signature is not going to give you brain cancer or whatever kind of disease or ailment you want to think of.
Blueblur, I question why you are trying so hard to get Thinker banned. He hasn't broken any rules. Yes, perhaps he is new here, yeah, he doesn't know the ropes, and maybe that could end up getting him a ban if he pulls moves like Arthur555, but I doubt he'll do that.
