The problem is that Bittorrent opens a lot of concurrent connections to
download many pieces at once. And all those "Tweak your Torrent client
and get mighty mighty speed" add to that.
The second reason to avoid Bittorrent over Tor is that there is no
audited torrent client. There is none because of the first reason. There
have been studies about various torrent clients leaking information
directly leading to the deanonymization of users (IIRC the packets
contained local interface IPs), and Tor cannot stop an application from
But, yes, in general it holds that the Tor network could use more relays.

Everyone has a "customized" operating system. Windows users not so much
because Microsoft's greatest failure was to never add package
management. Still, knowing about the updates itself is already a risk
for your anonymity. Ideally, all Tor users would use the exact same
version of some static operating system like TAILS, and update all at once.
