YouTuber ADoseOfBuckley recently published a video that discussed censorship and the video subscription service, OnlyFans.
At 6m39, he shows what he purports to be an excerpt from the OnlyFans Terms of Service. While he doesn't mention it, the text includes an admonition not to upload content that show, promotes or refers to "extreme fisting" (Caution: Even the Wikipedia page about the sex act may not be safe for work.)
I'm just astounded that an international company needs to have fisting regulations in a TOS. I find the whole thing rather surreal and was wondering how real it is.
