repayment scam:

Provider meets in the parking lot of an apartment complex or hotel.  She says that she needs to pay for her room or to pay her roommate to use the apartment or that her roommate will be evicted unless she gets money in advance.  She will either claim to rent the hotel room or pay the person in the apartment.  However, once she gets the cash, she walks out of site to a waiting car and speeds away.

 
Fake pic scam:

Provider using fake pics is either a sting or she is planning on ripping hobbyists off.  She is not accountable for reviews without showing a full-face picture because she can merely put a new fake pic and a new burner phone and repeat her scam ad infinitum.

Also LE uses fake pics and/or non-face pics.  They will not send face pics or topless pics because the prosecutor will not prosecute the case involving nudity, which includes a topless pic.  Note that side pics or sexy pics with the nipple being covered and also ass pics are not legally considered nudity so they will come close but not cross the full topless pic line.  Therefore the topless pic is important.

 
Full name scam:

Providers or LE ask for full name and/or to show driver’s license.  The full name is used to file a criminal complaint for prostitution or to extort or threaten the hobbyist.  

 
Outcall scam:  

Provider will have a security driver and attempt to rip off the hobbyist by getting the money and running out.  Also there is another version of the security driver breaking in to the house during the session.  Any provider using a driver should be sent away.  Ideally drive the provider yourself because a variant of this scam is for the security driver to drive in a second car and then break in during the session
