Unpopular opinion, but I think that any website owner accepting uploads from strangers should bear responsibility for those uploads. You cannot just say "not mine, I just distributed it".
UPDATE: Unpopular because it means there's a lot of work for the owner to moderate the files. And large sites like facebook are notorious for very bad moderation. It's not like we mandate them to hire N moderators per M users.
When running an actually competent LLM is as cheap as a $10/mo cloud server (for the moderation), I'll actually agree with this sentiment. Probably wont be unpopular long beyond that point in time.
There's a middle ground for this though. Platforms like Youtube, Facebook, etc, have no excuse anymore. They can literally scan with these models they have available and handle it. So write the legislation based on their capacity so you don't screw the one dude just trying to support some indie game devs in a small community or something.
I'd be fine if that were the law. What really frustrates me is the double standard where I can't host something that Microsoft or Wetransfer can without repercussions
