Comment (by SergeyBiryukov):

 Hi there, thanks for the ticket!

 Replying to [comment:12 minimoo]:
 > I'm just imagining that someone may have made their username www.yyyy
 .com-admin or similar in the past, which then would no longer be valid
 after the wordpress update?

 Indeed, we should be careful here, as both `www.` and spaces have been
 historically allowed in usernames.
