Not only is it very much against Pornhub's rules, it could be a felony in the US.
Anyone who appears on-camera in a porn video needs to provide the maker of said video with copies of their legal identification showing that they're over the age of 18, as well as fill out some paperwork compliant with 18USC2257 regarding said IDs and some other personal information. Not only are the "models" in these videos not verified to be of legal age, but there are no IDs on file or 2257 paperwork OR any proof of consent. Non-consensual material is against the TOS of every legit clip site on the planet, and not having that paperwork is a felony. "But it's not porn!" - that argument goes out the window when the video hits Pornhub.
From what I'm reading from both Monkeydudets2 and Phineas,this is a first to hear since many of those tickled ladies in the stocks are 18 and over (in those clips that are 20 to 25 years old[since a majority of those clips were filmed in the late 90s to the early-to-mid 2000s]) and any of those renfaire compilation owners(such as Marco[the man who sold renfaire compilations years ago]) haven't singlehandedly filed any major lawsuits against adult forums(such as this one) and video clip sharing places(such as YouTube and Pornhub) or have ever enabled the law to have those clips immediatety taken down,otherwise these clips would no longer be in any form of existence. I am not an expert on neither law nor the history of the people behind the renfaire compilations,for this is what I'm just assuming(regarding the renfaire clips situation).
