Just reminding you that non-ASCII characters are included in most European languages (umlaut, accent....etc.) using Latin scripts.
So, consider that when you take your decision to ban those emails too.

Precisely. As a forum admin, I would cheerfully ban all non-ASCII e-mails for registration, because my user base is not world-wide, but the spammers are. Only reason I am not doing that today, is that the software doesn't know about non-ascii e-mails yet :)
