I think you're taking other people's opinions to seriously Damien. We can't see the comments on your reputation, so just treat it as you feel it deserves.
In my view, it's a rather cowardly way of taking a shot at you regardless of what you may or may not have said, and I'm sure that if you probably PMed one of the Mods they would seem that the right thing was done.
Don't give the person the satisfaction of knowing he's upset you.
Obviously he never read your signature
