Ditto on this... I also wonder how this meshes with "You can share just about any kind of link in FlingUp." and "Anything goes on FlingUp." (from the tour)

It seems as though users may share links to whatever, but only content which they own. A difficult line to tread.

For the op, I would ask for a little more clarity on the intent.

(N.b. this might cause some issues posting AI-gen content, which is sans copyright by law, at least in the US. Maybe that's the intent?)

A rewrite is in order with clarifications. The intent is to minimize risk coming from users submitting copyrighted content (entire news articles which are behind a paywall, for example, pages or entire books etc) which could backfire if the organization/site grows. IANAL but this would have to be looked over by a proffessional.

That makes sense, but why don't you let people submit their own content? For example, if someone has a webcomic or a blog, or a photography site, or writes tutorials, or is making an amazing new app... Surely that's exactly the kind of thing that you want. Or at least an important part of it. As it stands it looks like you're saying only other people who find the webcomic (for example) can submit it.
