So, is this only a problem if you use Bittorrent over TOR
Or is this a problem when someone is using Bittorrent or another p2p program over TOR? Or is this a problem when someone is downloading a file over TOR that might take a long time to download because of the speed limitations of TOR via FTP?
If the latter, yes, there is a hell of a reason to be exceptionally concerned here. Not just for people doing illegal things via TOR but for regular TOR users like myself as well.
