Where are you finding providers?  Rub Rankings is full of frauds!

on Tryst, you can add a filter for service type and pick FBSM

I’m not sure what city you’re in but in San Diego for me I use Rub Rankings.  I have over 2 dozens, if not more that I have repeated seeing from that platform.

but they've fallen hard in the last year. The site is now mostly fake reviews and the mods have removed the ability to list what services the girls provide. On top of that they had the nerve to raise the membership rate. Right now it's a wasteland for finding credible AMP reviews.

USASG used to be good as well when “Jackson” managed that site.  It’s a free site and now mainly has posts by shills with multiple handles.  That A2 is a dbag!  He said he’s try to get raid of shills but still has the most known shill of them all posting reviews, etc.  The A2 banned this shill 2-3 times under other handles but is now keeping him as his little pet!  The A2 uses double standards that suits his interests and doesn’t follow the site guidelines.  

10000% agree. I left USG because of that douchebag A2. I found out a poster there was claiming a girl I knew very well did way more than she actually offered and called him out about it. So of course A2 sides with him and tries to start some shit with me. I told him/it basically to go fuck himself and left the site. Never looked back. AFAIC, both RM and USG are now garbage sites full of shills & fake reviews and are to be avoided.
