I have gotten upset at signatures before. Insane Anakin called me the Anti-Christ in his sig and for his refusal to change it, I banned him. Then there was the small tale comment in German...personally, I think it was a decidedly odd sexual innuendo, but on the advice of others, I did nothing. It was changed shortly thereafter. Those were sigs that were attacking one person, and rightly they were dealt with. However, what we have here is an idea that some can express a belief about themselves (see the recent examples of "I am..." signatures) and be banned or warned for it. I am glad an idea as idiotic as that is being overturned and actually discussed for once.
