Gmail a popular address generally.

It isn't quite clear what the problem is. Do you:
1. Have a lot of spam spoofing gmail accounts which is quite distinct from genuine registrations?
2. Have spam which is spoofing registration requests?
3. Think that a high proportion of genuine requests from gmail customers may be from people who will then spam your forum?
4. Have requests from gmail customers that appear to have been created by a bot?
