I was actually thinking that. New members wouldn't know that the 'moron' title meant they were banned. But I'm pretty sure the administration team couldn't care less if the new members had any idea who was banned and who wasn't.
It's a valid suggestion, but I don't see the need to change how it is now. We've had it like that for so long...I'm sure most people are aware that Moron = banned. Besides, why would members need to know who's banned? Especially newer members.
I agree with Cody. It's not a bad suggestion, but it's not really necessary. It adds a bit of a novelty element to people's stupidity. It's a pity the new members never got to see the chaged signatures though.
