We are aware those sites exist. Periodically we still get people affiliated with them, like Tabitha, to post here for a week or so before they are banned again. These sites are the reason why there is a "How not to out yourself" link in the welcome message posted as your registration is acknowledged. You should also know that several of the people behind have also been outed; although the tradition on GC is that we cannot post their details here (you can do that on BC, though). I disagree with that but it's the law here and I will respect it.
