A coinbase spammer seems to have automated the signup.

I've removed 342 users who are not just using the forums, but are advertising in their user account bio information too.

Please keep me up to date with large spammer action as I must delete their accounts, not just ban them from the forums to remove their impact.

Signups by this spammer and ongoing, I see them now.

OK I've added three new spam protections:

1. You can no longer reuse the name email address for multiple accounts
2. Any username with the words 'support' or 'help' will be rejected.
3. Any first name or last name with three numbers, with no or any non alpha separators will be rejected

Users will no longer be told that their registration form or profile form tripped the spam filter, it will instead just sit there saying everything is fine, while not allowing the form to be completed.
