I actually saw this a few months back, but didn’t do anything with it until Kurt Wismer reminded me of it. It’s a G+ post by Chris Blasko on how he used his ‘powers’ as a sysadmin to disrupt a telemarketer. I don’t advocate vigilante action as such against nuisance callers, for a number of reasons, but I have to admit that this was a highly amusing example of social engineering. As Kurt remarks, it would have been even funnier used against a support scammer.
