It is not so much that they are incorrect. What is incorrect is to force 
the takedown of Tor exit nodes because of - in comparison - little 
abuse. And after all the Tor relays are not the origin of the 
infringement and actually protected by the DMCA (512a). Still, upstream 
ISP don't care much and want the complaints to cease.

In that sense, the takedown requests *are* incorrect.

You cannot "exclude p2p" if as with Tor exits policy is port based. 
Bittorrent (which is the main culprit here) uses port 80 (or 443 for 
SSL) for tracker connections, and random ports for actual transfer.

If you cut of tracker connections (by blacklisting them), abuse stops. 
If you stop the actual transfers from happening, abuse stops, too. Both 
MediaSentry and BayTSP refer to the infringement including the port that 
the data was offered on.
