Regarding the legality of scraping factual data... In the EU there's a 'database right' that covers specific collections of facts. The US has categorically refused to issue any kind of "IP"[0] on facts, and doesn't have 'database rights', but in practice you can sprinkle a few fictitious bits of information in your dataset, retain copyright on the lies, and sue people who don't independently verify the factuality of every bit of information in the dataset. So the US has database rights. No clue if people are sticking fictional data on their websites to sue scrapers with, but I wouldn't be surprised if they were.
