Inside Pornhub
From the article:<p>&quot;I often encountered videos that were uploaded again and again, no matter how many times I removed them. One day, a woman emailed me, calmly explained that her ex-boyfriend had uploaded a video of them having sex, and asked me to remove it. I deleted the clip. Later that week, it was re-uploaded. The woman wrote again, I removed it, and this continued for months; I must have pulled the same video down a dozen times. This was before I had ever heard the term “revenge porn.”<p>Requests like this were not uncommon. Once, a woman wrote to say there was a video of her on Tube8 that showed her being sexually assaulted after someone spiked her drink at a party. The video had tens of thousands of views, so I had to review it before making the call to remove it. In the clip, the woman is clearly high, laughing and head lolling, having sex on a bed surrounded by fully dressed people holding drinks and watching as colored lights flashed and music blared in the background. I took it down, but it was uploaded again repeatedly in the following months. Each time, the mortified woman flagged it, and each time, I removed it; both of us were aware that there was nothing we could do to stop the clip from resurfacing.&quot;<p>I have read the same thing from Facebook content moderators.  They got so frustrated at having to watch and take down the same videos over and over.<p>This seems to be such a simple problem to solve:  record a hash of the video file, don&#x27;t allow uploading it again.  That would probably get rid of most re-posting.<p>It could be bypassed by modifying the file slightly, but the hashing could also get more sophisticated.  At some point, an ex-boyfriend is not likely to want to keep modifying a video to piss off his ex.
