Using AdSense For A Personal Vendetta

When I was in Gmail the other day, I was a bit surprised to see the following ad:

Yes, the link was to a web site giving all kinds of reasons why one should not do business with this person. I am not going to link to the site at all, but a quick Google search should bring it up if you’re interested.

I am not going to comment on whether or not this person is or is not a “deadbeat” because, for all I know, this person isn’t and this is just a libel lawsuit waiting to happen. Even so, it’s really interesting that a person (or a group of persons) would use AdSense as a way to get back at someone that did them wrong.
