I think there was also case law about this recently[1] regarding LinkedIn, where if the content isn't behind a login wall, it can't legally be considered anything but public. The UGC aspect is an interesting angle I haven't thought of, but that's a fantastic point too. Would I be correct in saying that the same mechanism companies set up to evade responsibility for illegal UGC also sets it up to be legal to scrape? And if the user owns the material, what happens if you've already made money selling that data and they ask for their cut of the proceeds?
