I've hired providers on Grindr, Instagram etc that have Rentmen profiles. In all cases on the social-hookup platforms they didn't advertise they're a provider, and usually I'm quoted a rate lower than their RM fee.
In my city it's normal to see providers on dating-hookup apps. I just keep the two avenues separate. If I come across a provider on Grindr and am interested I'm reaching out to hire.
