You are probably guided by the false dilemma presented by that or similar articles. I doubt any porn service on the internet in the last 25 years did anything like that, just like no web hosting service has checked that each image and each piece of text on your web site is legally owned or distributed by you. This is by no means a recent problem, naked pictures were leaked intentionally or unintentionally long before internet existed. However, the discussion implies that all of the sudden porn sites appeared, you can be on them, and wegottadosomethingfast!

I don't think there is much difference between your naked body and other information you might want to keep private. “Porn” triggers people (most often American people, I have to admit as a distant observer), makes them reason like there is some inherent difference between “porn” and “not porn”, and makes manipulation easier. Basically, what you're saying is that there should be more (indirect) censorship and real-life identity matching on the Web — but it's for an Obvious Good Cause! The problem is that Good Causes get forgotten quite fast, and the one who benefits from it is the entity in control of the system that gained power. Here we have porn studios dictating previously independent Mindgeek (former pain in their asses) which content should be on the biggest porn streaming sites under new system. The speed and scale of the attack, and the concerned voices from various directions, hint there was a lot of high-level lobbying involved.

Here's no less thrilling example. Suppose that Rick Astley wakes up tomorrow and decides to point out that he has always been a singer and not some kind of internet joke. Perfectly understandable impulse. Then he proceeds to remove all the non-musical uses of his songs (let's forget about corporate ownership). How would you react to that? What would results be? There's certainly more people with similar wishes — basically the whole genre of “viral videos” is one big zero consent heap. When you are having a laugh at someone's expense, do you worry about them? When you watch videos of Beirut explosion, do you think about all the dead people who never gave consent for their last moment to be your entertainment? Should we ban the uploading of such videos without explicit source checks, then?
