If you're going the BP route you should keep in mind that if it looks TGTBT, then it most likely is. If she doesn't have reviews, a website, or ads on other places that have a decent reputation like P411 and D/C, in lieu of a website, then you might want to pass.
Also rates that are too low should make you take great pause. It's possible it's not really her, LE set up, or something else that will simply not end well. IE: posting 60 dollar specials who look like a 10, follow the TGTBT, not ending well rules and pass... lol.
In some smaller towns BP is the best resource for ladies to advertise because it's the only place. I notice well-known ladies posting on BP in smaller areas but they usually tell you their website in their ad. Which is another good way to spot a non-fake when you see great photos.
Tineye is also your friend for those photos that are TGTBT. You can sort out the fakes easily that way. Alway play back your findings to the community. You're doing yourself and others a huge disservice by not relaying info and not writing reviews. Good, bad or indifferent, share it.
