All we can do is verify the information that's provided to us by the rights holder. That includes the time, date and IP address of the downloads. When all that information is accurate, we forward the notice, and we're obligated to do so.
I can understand it's a concern for users, and that's why we want to ensure there are new provisions that ensure that we can at least weed out some of the more nefarious ones, but there will always be notices that are provided that.... It's supposed to serve an educational purpose, and sometimes it just doesn't hit that mark.
