So who will decide what constitutes a BL here?  The NoLA  hooker with some fat guy?  A DC hooker pissed about a shitty review?  A ChiTown hooker pissed about some asshole who comments on her posts that she's a nutcase?

It would eventually devolve into the silliness at NBL.  The best methods still are to network in the game....both for hookers and johns.  Sure, some of the backchannel may be BS...but it also isn't that tough to realize who is real versus who has an agenda.

And if all you used here was some johns handle...BFD.  That handle goes dormant and a new brown envelope followed by new reviews will appear.  So what have you accomplished?

In a perfect world that is great.  But until the asinine 10/10 fake hooker ratings are brought back to reality...I think trying to determine a potential dangerous johnnie boy is just as unrealistic.

All kidding aside, SHE is the one who should be blacklisted. TER takes provides who make threats very seriously, and if you can prove it, they will most likely ban her ass. I don't think they are going to want the added hassle of a BL site, but if you or anyone else is being blackmailed for good reviews, they will hold that provider accountable. Make sure you keep all correspondence that shows she has made such threats, and forward it to them. I had a friend from Ohio go through this and the girl was banned. She actually called his office and told his partner about their little escapade because she was pissed that he told the world her pics were outdated.
