I tried them once and it turned into a disaster. The girl was nice and we remained friends, but the boss man took advantage of her at every turn, including not paying her more than once and using her image in outdated Backpage ads without her permission, which remain to this day even though she hasn't worked for him for over half a year. Dude even once gave my number and personal info to another girl without informing me. She apologized and was embarrassed but obviously I didn't hold it against her. Wasn't her fault and she also quit a short time later as my friend did. So I told the boss it wasn't cool and he gets hostile like he was doing me a big favor. I told him to piss off and start treating those girls with basic common decency. Their parent site is Snuggle Buddies (recently getting negative Yelp reviews from a client and former provider), which claims to be holistic therapy, except many of those girls do both the snuggle and fetish work. Also, take a look at the fetish site's price tiers. Masturbation? Really? I'm no legal eagle, but even I know achieving sexual gratification in front of a "provider" is a bad idea. Somebody is going to get hurt, arrested or both.
Quick edit: Plus, $100 for a provider is a joke, especially given it gets spilt between them and the website. Assuming the owner doesn't keep embezzling their share, mind you. Not worth the trouble or creepy Snuggle Pimp factor.
