Love scams on dating sites
These scams are lucrative mostly because they prey upon distance and anonymity.
Since a large percentage of men who visit these sites never actually end up making a trip, the agencies can really rake it in without getting caught.
She'll just say "Hi, I saw your profile at the agency and you seem like the perfect man for me..." (but failing to identify the agency).
You may think it's just a big dating website, but in reality it is a network of local agencies.
The most obvious indicator that you're dealing with an agency or agency network is that you pay for each message to any girl to whom you write, and usually you must pay for her reply (if she replies).
That's a little frustrating to me because scams are so easy to avoid.
Far too many men become obsessed with determining if the woman with whom they are currently corresponding is "real" that their quest to find a partner never reaches the step of making a trip to meet REAL Russian/Ukrainian women.
