I know your reasons for stopping signup from free websites, but there are other ways to do that. I know of some other Online Games that allow Free Web Addresses, such as Pardus or Nationstates. What they use is a tool that checks your IP when you login. If you login from multiple accounts from the same IP, the accounts will be warned, and if the Offender Continues, the Accounts involved get Banned. Why Can't you use this instead? Some people are willing to play, but don't have the time or money to go through the time and trouble of making or finding an Overpriced Website for E-Mail. I hope you consider this.
