Via Understanding Google Maps & Yahoo Local, the words of a Locksmith recently banned from Google Maps:
After that many of my claimed listings got hijacked by my competitors, I knew I’ll crack the method to do it myself & that I’ll send you my revelations in order to shut down this option.
So we have a locksmith who considers it acceptable to test and defeat a company's security. Does he also walk up and down the streets in his home town trying to break into buildings?
Is there no Locksmith Oath?
