I can think of some questions off head and will list them : Can the
mail be legit, I'm still on the fence.... The ip ( masked ) is
information obtained using what method, if the sentry is using mining
or striping then itself in infringment.  Does US laws allow hacking of
hosted systems to obtain such info? Under what laws is the company
allowed to eavesdrop, since piracy is not a national or international
threat under their laws. It may only has proof of an IP and may have
obtained data which I think under some laws would not be acceptable
methods. I'm only writing this as a light-hearted joke: Find a good
lawyer and sue them for infringement of privacy rights!
