I think brokers are free to do whatever they want with their customer's data (at least in Russia) so this could be possible. Also the guy could be making up all this data and randomizing part of it...
Yeah they did reply in less than 24h! Shoot your questions but I bet they won't give you the broker name! Keep me posted, I'm really curious to know more about them.
EDIT: about the data don't get me wrong, no brokers in the world can give out your passport, ID, proof of residence...Etc (obviously). I'm thinking more about something like Facebook who sells the 'tendency of their customers' in a anonymous way.
