Comcast making bitTorrent seeding impossible; Cogeco, Rogers doing something similar

A few seconds after you connect to someone in the swarm the Sandvine application sends a peer reset message (RST flag) and the upload immediately stops. Most vulnerable are users in a relatively small swarm where you only have a couple of peers you can upload the file to. Only seeding seems to be prevented...

But without seeding, I think trackers tag your crap ratio somehow and you get hit in some fashion; just get booted for the private ones, I guess. Cable provider Cogeco and Rogers are doing something similar on a smaller scale.
