I have a business associate that has done some pretty rotten things to me over the last year. Everything he did was legal, but it was very underhanded and shady. He feels he is untouchable. This guy has cost me over $100K. Let's say, hypothetically of course, that I wanted pay him back. Let's say I might want him fired from his company or his reputation ruined. Using what we Blackhatters know about the interwebs, hypothetically, what would you do?
