They purged everything for unverified uploaders in 2020:

"As part of our policy to ban unverified uploaders, we have now also suspended all previously uploaded content that was not created by content partners or members of the Model Program," Pornhub said in a company blog post, as first reported by Vice. The purge appears to have hit almost 9 million of the 13.5 million videos on Pornhub as of Sunday, or nearly two-thirds of all the content hosted on the site.

"This means every piece of Pornhub content is from verified uploaders, a requirement that platforms like Facebook, Instagram, TikTok, YouTube, Snapchat and Twitter have yet to institute," the company added. "In today’s world, all social media platforms share the responsibility to combat illegal material. Solutions must be driven by real facts and real experts. We hope we have demonstrated our dedication to leading by example."

The swipe at other social media platforms is no accident. "It is clear that Pornhub is being targeted not because of our policies and how we compare to our peers, but because we are an adult content platform," the company added. Citing Facebook's transparency report, the company added, "Over the last three years, Facebook self-reported 84 million instances of child sexual abuse material. During that same period, the independent, third-party Internet Watch Foundation reported 118 incidents on Pornhub. That is still 118 too many, which is why we are committed to taking every necessary action."
