Well this is interesting.
My email address is actually in the database.
I do a search of my email box and find a 2005 email saying "thanks, we've deleted your account".
I have no recollection of ever signing up for the site and the delete account message was unread.
I won't out put of the realm that I made an account to do a search or something 10 years ago when the site was a new taboo thing. But honestly I don't think I did. And the site doesn't require email confirmation to sign up, it just takes your email.
Barack.obama@whitehouse.gov is in there too.
Apparently only people with credit cards in the system could contact each other. So those are the only real users. And about 95% don't seem legit.
But I'm sure in another 10 years ill be answering for this to someone despite the details here. Oh internet, you so crazy.
