The whole "we're just a platform" thing makes it incredibly easy for Pornhub & co to just say "wasn't us, it was some user" and not even handle the deletion process on their affiliates' sites (who they provided the video + images to). It's like Mega Upload, which was obviously made for copyright infringement but successfully hid behind the platform-excuse for years.
I'm not a friend of far-reaching regulation, but it seems that we don't have sufficient processes in place to deal with these companies unless there's gigantic financial interest involved that makes the state feel motivated to intervene.
I would argue the copyright argument goes the other way. If you're a big vertically integrated corporation who has greased the right cogs it's incredibly easy to get content taken down wholesale without any oversight or accountability. Whether it's having content removed or restored, the burden somehow always falls on the individual.
