Maltego mines the Internet without violating TOS

Not long after reviewed Roelof Temmingh's powerful online data mining tool Paterva Evolution a few months ago, Temmingh was forced to remove the application from the Paterva Web site because of complaints that some of the methods he used to harvest data were violating the terms of service (TOS) of the services from which the information was gathered.

Recently, Temmingh released a completely redesigned version of the tool -- now called Maltego -- and has made it available again as a free-as-in-beer download.
