I don't think that there's many people that would buy a banned account - Why should they?
No E-Mail? No SQ/A?
You won't get it sold - Just the E-mail is a NEED to get it sold, mostly, the SQ/A also.

Edit:
You could of course try lying about it being banned - Probably also about the E-mail/SQ/A..But I don't know how that would turn out.
