Maybe "hypocrisy" would be a better word. That said, there are lots of reasons why this doesn't mean that he, personally, is responsible for this and why the information in there may be inaccurate. I believe the HN article on that service had quite a few people pointing out that the results returned by that site were inaccurate. And sites like TPB are known to return false peers, so naively scraping the list of peers is not a good way to see who is downloading what.
My guess is that it never originated from the actual place, but was spread nonetheless by some people. The point is probably to show that finding the ip is not a reliable indicator. As opposed to the three strike, which is relying almost entirely on identifying someone from his ip, on such places.
But if the tech to reveal who is downloading comes out in the open, it will be a good thing. The industry is apparently already doing something of the sort, but may not be doing a very good job. The only way to achieve rational thought will be to shine a light on them as well.
It'll be funny. But it'll also probably have an affect on court cases.
