Sounds like an opportunity to take down MediaSentry.

The "takedown" notices state the following:

] On behalf of <copyright holder>, owner of the exclusive rights to the
] copyrighted material at issue in this notice, we hereby state, that
] we have a good faith belief that use of the material in the manner
] complained of is not authorized by <copyright holder>, its respective
] agents, or the law.
]
] Also, we hereby state, under penalty of perjury, under the laws of
] the State of California and under the laws of the United States, that the
] information in this notification is accurate and that we are authorized 
] to act on behalf of the owner of the exclusive rights being infringed
] as set forth in this notification.

Given the references to "good faith" and "perjury" in the above text,
if the data collection methods employed by MediaSentry are
demonstrably faulty, falsely implicate source IP addresses not
actually participating in file sharing (not a spoofed BGP route,
rather a bogus entry in the Kazaa or eDonkey indexes showing the wrong
source IP), MediaSentry may no longer be protected by the "good faith"
clause?
