I think it'd be a good idea to add the precise date creation of a user, instead of just 'October 08', it'll probably give people a better idea of spammers, and it can't harm anyone?
What does it matter?, besides there is one, but it dosen't show the exact date. I honestly disagree with your suggestion, waste of time and space in my view. Also, it's a small thing to worry about in my opinion.
