Yes, we do have experience with OnlyFans! 🙋♀️🙋♂️
Our page: OnlyFans.com/BruceAndMorgan (it's mostly piss drinking and golden showers though, so not sure how much people here will enjoy)
We joined 3 months ago, after resisting for a long time and seeing everybody we knew in the adult industry migrate to it. Although their terms and conditions are pretty clear about urine content being forbidden, we saw that Charlotte Sartre (onlyfans.com/gothcharlotte) was posting it and labelling it as "p33" or similar, so we are doing the same. Most pee-related words are blocked, so we use p!ss, g0lden shower (with a zero) etc...
I guess we expect to eventually get an angry message from an OnlyFans employee requesting that we delete all our pee content, but for now it's really great. People are friendly, and the reduced price compared with our main site means that it's easy for people to subscribe. I don't even think the OnlyFans people have a huge moral issue with hosting pee content - like everybody else they are afraid that their payment processors will drop them for fear of pissing off the credit card companies (something we've been fighting every step of the way, but that's a story for another time!).
Although I suppose some people are abusing the platform like @Dtravis mentions (ex: making people pay a monthly subscription and then charging them extra for every video) in general we see a lot of smaller producers getting their start there and seeing some success. It's not easy to generate income when you're just starting out, and OnlyFans really nailed the experience. It's simple and cheap, and the feed concept is a nice way to feel like you're staying in touch with the person you're following.
