"Levi Goldstein, Sydney" and i get a reply that says bongo thinks "Levi Goldstein is a Mixed Raced stud an these two girls just think he gives good loving' " how did it know that i was mixed race and secondly he names two girls whom i know personally?

Probably uses social media sites and information from the web it can get about you. I'm not sure though.
