That's my question, too - I thought OnlyFans was a hosting platform for personal porn sites; I remember there was a big uproar a few months back when some TikTok influencer joined the site and started posting non-adult content. People were upset that they were diluting a site that's specifically for adult content.
Not quite accurate. Bella Thorne joined Onlyfans and promised "no clothes naked" content in exchange for her $200 subscription fee. She made millions of dollars but then only sent clothed and obscured pictures to her subscribers. After thousands of people demanded refunds, Onlyfans changed their policies to heavily limit how much subscribers could be charged for content, how much they could pay, and increased the creator payout wait time from one week to three weeks. This heavily damaged the incomes of thousands of people overnight.
