People are saying this guy accessed databases illegally, but what about Shodan? They crawl, port-scan, access, and index everything they can find, not just HTTP servers. They are what made it possible for this guy to find these unsecured databases in the first place. They even counted the total size of the exposed databases' records.

Why isn't Shodan being sued to pieces for illegally accessing private databases and being a "Google for black hats"? I've even found them port-scanning my home DSL connection.
