Notice of Claim of Copyright Infringement, pt. II

Almost to the hour two months after the last email ("Harry Potter Audio Books", yeah...right) I got contacted again. This time someone thinks I'm distributing "Iron Man 2" (again, srsly?). The Tor legal FAQ was helpful as always, so...let's see how this one pans out - if it does anything at all, I haven't gotten any reply to the first letter yet (apart from a Zimbra-mangled auto-reply). Is this a good sign? No?
