Zillow pulled out the fucking CFAA??? That's just plain dirty.
The CFAA makes it unlawful to exceed authorized access to any protected computer system (essentially, any computer in the United States). If someone claims that you've violated their ToS, they almost always also claim that by so doing, you've also violated the CFAA, since your access "exceeded authorization" as granted within the ToS, which they'll claim you've agreed to.
Now your breach of contract is upgraded to a federal crime. Better hope you don't make the wrong MegaCorp mad.
