The OP has edited his question so it should now be discernible.
In my opinion, some of the cues that a provider could be LE:
- She advertises on Backpage, Craigslist, or some other sketchy place.
- She doesn't have reviews from established, long-time hobbyists.
- She encourages you to talk about particular sex acts and dollar amounts for same.
COULD a verified Eccie provider be working for John Law? Yes, it's happened, but it's rare. The situations I know about involved a provider being arrested for having an illegal substance and working in a prostitution sting as part of her plea bargain.
