The main problem is they can't be bothered to figure out how newsgroups work, or pay a little money for the privilege of using a less network-intensive protocol with better performance. BitTorrent is just a drain on the network, and makes things like gaming impractical no matter how much you throttle it (though it certainly helps a lot). And people often leave it running for long periods out of civic duty. IP throttling isn't specific enough. I don't need to throttle an HTTP download that's going to be done in a few minutes. I just want BT to die on my network, at least when I want the resources free for other use. /rant
