I actually know of a real world case where someone did this. He was a news admin of a large Usenet service. He paid Google Answers to answer the question "Why is <name of his Usenet service> better than all their competition?" He asked a loaded question, and of course got a reply saying how great his service was. He actually posted his question, and the answer, to Usenet for humorous reasons. Of course, he could have hid the fact it was he who asked.
I think Brett ment the guy *asking* the question got his own site back as a answer.
I was almost tempted to do the same thing.
But I didn't :)
