Some ISPs, like Comcast in the USA, throttle or even block Bittorrent traffic in their networks. To get around this, you should change the options in yout Bittorrent client to use a different port than the standard 6881 and also force protocol enrcyption. If that doesn't work, use the Bittorrent download service from Imageshack.us, which allows you to upload a .torrent file and download the file(s) for you via Bittorrent. Afterwards you can download it via normal http with your Browser. A new service is Bitblinder, a anonymous Bittorrent client which is supposed to bypass filters.
Since Bittorrent is a filesharing protocol, it is also great to publish information on the Internet. To make sure it is difficult to censor the upload, use 3-4 different open trackers at the same time. When you create the torrent choose them as announce trackers. Most modern Bittorrent clients have multi tracker support. So when one tracker goes offline (or is censored), there are still 2-3 others where the client can choose from. Even when no tracker is working anymore, modern clients can download using the DHT feature. You can also use a free Bittorrent web upload service like VIPeers.
If you would like to see if your ISP is manipulating your Bittorrent traffic, Glasnost is a free webapp that similates a torrent to determine if the traffic is being slowed or stopped.
