That has nothing to do with the discussion.
it's quite hippocritical to say "Dont use that animation in your sig" if you have an animation yourself. Why can't he use it, other than the fact you don't like it? And does it really matter to him at all you don't like the animation? That should not affect his choice of putting it in his sig or not. A signature is based on one's personal taste, and you have no right to interfere with someone's taste simply because you dont like it.
