What does that have to do anything? The point is that users do not care if other companies copy their listing data (and aren't even aware of such a restriction).

How have you determined that every users listing on Padmapper doesn't care it has been scraped from CL and relisted? Did they contact every user and get their permission first?

It's not necessary for them to do so. It's incumbent upon CL to prove the infringement, not the other way around.

Under the HN logic prevailing in this discussion, that would appear to be correct...

But like padmapper, you would be completely screwed if it turned into a lawsuit.

Exactly, ignorance of the law is never an excuse! THen they make more laws
