Overview
BitTorrent as a protocol allows for peer-to-peer file-sharing of large files. Unfortunately, BitTorrent-related processes and software are not allowed on DreamHost shared servers. This can be seen on the Acceptable Use Policy.
Although there is value in the BitTorrent protocol as a distribution method, it is far too easily (and often accidentally) abused/misused and therefore not allowed on DreamHost Shared Hosting services.
