This plugin adds filters to the WordPress user registration process. It lets you check user signups against StopForumSpam.com and/or Emailable.com
When a user registers, you can configure this plugin to use the submitted email address and IP address to first check against StopForumSpam.com to see if there is a match to the IP address and/or the email address in their FREE database. Then you can check if the ending of the email address is .ru or another country extension you want to block to cut down on spam registrations. Finally, if it passes these checks, you can check the email address against Emailable.com to see if the email is valid.
