There are a few more, actually. A search for 'escort' on the username, profile_website, and profile_bio fields (after pulling down the list of all users) actually gives me 20 different profiles. Some are flying under the radar! (Also, my latest follower seems to be one. Cool!)

I wonder what the pay is to advertise these types of "services". Do the girls pay a fee? Perhaps the pimp (if they still exist) does it all or it'd be interesting to know what sort of firm runs the accounts lol
