I would suggest that you abandon trying to ban users based on domain, or IP, and focus on their actual content/contributions post-registration. As a bonus, by banning users based on content and not email address, you'll also catch those who use "valid" email addresses that you'd never be able to "rule out" in any predictive sensible way.Completely agree. It's like banning someone from a pub based on the clothes they were wearing the last time you saw them. -Stut -- http://stut.net/
