When I first started hobbying, the idea of reviews for working girls wasn't something I thought about. I took the plunge on many occasions, and fortunately everything worked out OK. But that was a different time, before NJ got so hot with LE activity. Eventually, I started looking online, found a few review boards, and finally settled on UG.
Nowadays, fuhgeddaboutit. I've been on a temporary hiatus from hobbying, but when I jump back in I'll only see providers that are reviewed, or have enough of a posting history on CL that I have a pretty good idea that they're for real. Too much BS, too many B&S posts, and a higher chance that a poster on CL with no history could be a police sting nowadays.
