I think scraping websites that don't require authentication is legal in the US nowadays.

Monetizing data acquired through scraping could run afoul of copyrights, so the love letters would probably only arrive once OP attempts monetization.

>I think scraping websites that don't require authentication is legal in the US nowadays.

The LinkedIn lawsuit resolved to that conclusion, though I think LI is appealing again.

It basically says the site can't take legal action against scrapers of public (non-auth protected) info. Still, there's nothing that says they have to make it easy for you, to include deploying anti-scraping measures, rate limits, redesigns and moving data behind auth.

I thought that USA doesn't allow copyrighting facts which to me numeric values certainly are.

OP Here! Yes I don't know the law well but common sense tells me that its one thing to copyright a brand, logo, movie, or anything creative, and it's another to copyright numbers on a database.

The only argument Zillow can against me (imo) is that I'm being a burden on their servers at scale.
