The problem with that is that that sort of policy makes the internet just cease to function. User-generated content makes up a massive portion of what’s on the internet, and it can’t possibly all be policed before being posted, unless you want to make a post on Bluesky or whatever and have to wait weeks for it to be approved after manual review. The law requires companies to promptly respond to takedown requests but as long as they do, they aren’t responsible for the content posted by their users.
