YouHaveDownloaded is a public database of who downloads what. Click the link and it’s likely to show some of your recent downloads.
They claim that they monitor 20% of global BitTorrent transfer. In my case they showed 1 file of several that I got recently. They didn’t show the dozen of *nix distros that I seed, so I guess that they don’t monitor some kinds of trackers.
But overall, I think that the service is great. BitTorrent downloads are public and anybody can see them, but awareness of this fact is very low. Various pay-up-or-else shakedown schemes popping up around the world recently raised it significantly, but I don’t regard them as the best way of educating the public…And they aren’t used in places where P2P is legal anyway.
What if you don’t want your neighbours, kids or whoever know your favourite
porn film genres?
Use more anonymous forms of P2P.
Wikipedia lists some.
Myself I recommend BitTorrent anonymised by I2P. It’s not the easiest to set up, but probably the biggest network – and size is important both for anonymity and amount of content available.
