From a cursory scan of the online profiles, I'd say TG is a venue for both out-out and prostitution (search for profiles requesting "generous men only" and you'll see what I mean) whilst at the same time being a place for relatively well-off but friends-with-spare-time-or-money poor people to find travel partners (the stated goal of the site).
I have no idea what the breakdown between those two populations is though!
