Assuming this isn't a lie, you only need an image and a paper with your username to be verified(archive)“@LailaMickelwait Before anyone starts freaking out that it’s Pornhubs fault, The listed examples in the thread are simply account verifications. MODEL Verification requires an ID to prove age and allow payment for the content produced. The fault is on the people who exploited the girl.”twitter.com
Someone in the comments called out the OP, stating that in order to be a model, rather than a verified user, you have to be at least 18 with a valid ID, which likely meant that the people she was working with spoofed an ID, and she and PornHub unaware of it, rather than PornHub outright letting a teenager get fucked on camera in multiple videos. Doesn't make it any less disturbing though, and goes to prove that their verification system (for models at least) is shit.
