Not much anyone can really do about the "grab 'em & slab 'em" pseudo escort web sites, especially since many are hosted overseas. The way they operate is on "clicks" that they sell their advertisers.
Adult Friend Finder appears to be behind or affiliated with many of the pseudos. Heck, they even repost some of the stuff on BP, which, to me, make many BP ads even more suspect than they already are.
But,
you can try to protect your images, to a degree, by "watermarking" the photos with a "slant diagonally across" watermark, such as your official website address or your particular email or phone. And, fwiw, if you own the actual copyrights of the photos, then stick a
©
circle c copyright mark on then and perhaps a DMCA warning might work.
Even worse than the "grab 'em & slab 'em" escort type websites are the "escort bust" sites that allege you have been busted by LE and may be working with them. I think only real newbies get upset or worried by that.
You are much better off being a regular on recognized and known public (and some of the private more local) sites in order to established your bonafide. (Speaking of which, I do appreciate yours!)
