CL's robot.txt file does not 'disallow' crawling the real estate section. So Padmapper was likely as compliant as Google.

No, this is just semantics.

The point is Google respects publishers' desire not to be indexed. Padmapper does not. Robots.txt is simply a common method for conveying that message. It's not like Padmapper could argue they didn't know CL was unhappy; they got a certified letter!

This is just semantics. Google respects publishers who do not want their sites listed.

Good luck explaining that to a judge. Would you gamble a company based on that distinction?

True, but that's irrelevant to the comment I was replying to. We are talking about user expectations with regard to content they posted being made available on other sites.
