do you know anyone who uses Only Fans for G-rated work?
OF was originally designed not for adult content, but just sort of another Patreon. I've been thinking about starting a Patreon, but I think it would be funnier if I started an Only Fans since I make educational content.
do you, or anybody that you know, use Only Fans as if it were Patreon?
The only people who I know that do are people that are paid by Onlyfans to do so. To keep their image "Not just porn!". I've never seen anyone there who isn't there to make adult content.
Whether it started that way or not - it's now de facto a porn site. I think your idea is funny, but you're not going to get many subscribers compared to patreon. Most people don't want an onlyfans account because of the stigma. After all, if you post an update, are your subscribers going to want to have to explain to their wife/husband/SO that the email notification they got of a new post isn't what they think it is?
