>> How many new pornographic video uploads per day does PornHub actually need to serve it's audience?
As much as possible? It was 13 videos per minute in 2019. Each minute almost three hours of content are uploaded.
>> And the vast majority of content on PornHub likely falls into two categories: Major brand videos, in which they can work directly with the legal entities responsible for them
This assumption is very natural, but days of professional studios are gone. There are about 100 thousands amateur models registered on PornHub.
>> For the latter, a slower, non-automated approval process is probably perfectly fine.
Even if we'll estimate that just half of content is amateur, which is not so, PornHub would need at least 100 moderators working simultaneously at each moment of time to review every moment of all uploaded videos. I don't think anyone can view porn for 8 hours per day, so it's at least 4 shifts. Take into account vacations, and other things, that is easily 500-1000 of trained moderators who will know specific of genres, and will not punish fetish performers. And they'll need offices, computers, help of psychologists, security check because they can be source of major leak. I think we are talking about tens of millions dollars now.
>> my guess is a large portion comes from established adult film brands
There are big BDSM brands like Kink, but if you sum up minutes of content, it's mostly amateurs.
>> If PornHub works directly with the actual people filming the video, verifies performer age eligibility and consent, and then approves the videos, there is no problem with the content of the video shown itself.
So PornHub now has to perform full KYC, because US citizen would not know what Hungarian driver ID looks like. This is not a cheap service at all. And also PornHub now has verify that videos posted contain only verified identified models, which I have no idea how to perform. Also, now you enforce PornHub to keep a lot of Personally identifiable information about all performers which does not sound like a good idea in the first place.
>> Unchecked open upload of whatever content a user has on their computer has no real need to exist here. At the very least, every video should be associated with the performers present in the video, and upon the revocation of consent from that performer, all of the videos containing them could be removed and prevented from being added again.
You will just punish PornHub for being big, there is no way to enforce right to be forgotten across entire Internet.
