Fck, my bad, you are absolutely right. Fixed my comment.

Even if the traffic of the torrent protocol is peer-to-peer, there have to be central nodes managing all that unfortunately. This is why DMCA notices are also successful with torrent providers. Without anyone providing that central node, no torrent works.

One of the major weaknesses of bittorrent.

Edit: the solution is called DHT and I was a morron totally forgetting about that.
