Any idea how this thing works (if any)?

Is it basically a DoS where it just simulates an overwhelming number of fake clients that send garbage data at an incredibly slow rate, or something more clever?

This looks like Pirate Pay is injecting multiple sybils into the DHT with node-IDs close to the info-hash of the file, thus making the sybils responsible for the file. This assures that all queries are sent to the sybils, allowing the sybils to sent out false information to the other peers. A couple of years ago, some of my colleagues did work on this in the context of p2p localization. Their paper [1] describes their results in much more detail.
