If a pimp showed up and saw a camera crew he would immediately pull a 360 and book in the other direction. Most hookers would probably do the same.
Only experience I ever had anywhere close to that was when a girl's driver started texting her like 15 minutes early. If some dude was ever actually knocking on the door I'd have been tossing the girl off of me and going for the knife I always brought with me, but the circles I ran in were very different from the circles J49 is part of. If we ever found out a girl was being managed by a pimp we'd make some effort to get her free of him and if she wasn't interested she'd be ostracized with the drug users.
Pimps are bad news.
