I have been a member of Travelgirls for over a year now and most of the girls on this site are scammers and or hookers... But to their credit they do delete a lot of undesirables... One method they use to weed out the baddies is to ask every girl to have a picture taken with a sign "Travelgirls" on it to authenticate that the girl in the pics was actually them...
I found one girl who was deleted by the Travelgirls admin had downloaded her pics from a Thai porn site... This is not a free site...
