These fear mongering comments always ignore the notice provision in the CFAA. Web scraping publicly accessible information is not "illegal" under the CFAA. That law, at most, only makes someone who continues scraping after being asked to stop potentially culpable.

Is it possible to build a solid CFAA case when those two things do not happen? I cannot find any examples.
