The other way to look at it is that, if you've found an ATF, or even a favorite agency, do you really need full access to the site?
I enjoy reading the stories, sometimes, but if I know I will be going to CP or Sun exclusively, why do I care what's happening with Saigon?
And if I need the information for whatever reason, I can pay, or maybe review the last CP session I had. I'm betting the people running the site are far more interested in my money than yet another "Yoko is awesome" review.
BTW, she is awesome, but I actually think too many great reviews can be detrimental. Drives a lot of business her way, which, if she's getting too much, could lead to her getting burnt out and quality dropping. She may get an inflated self esteem, which is good for her, but bad for us when she raises her rates. Also, if she's totally booked up, how can I get in, lol?
