In registration, how do we block the use of email address alias (adding a plus sign to username) especially in hotmail and gmail?
We are infested by spammers using that trick to generate quick email accounts.
Is it possible to allow only alphanumeric characters on email address field in registration? No dots, no + sign, nor any other special characters. Something like Username Regular Expression in ACP > vBulletin Options > User Registration Options
