confused

[cglace]

today i recieved an email from my internet provider that i was reported to them for a copyright infringement for a download from limewire. i checked this download and it is not copyright protected. i have the filters set up now and checked to see if i could download it again and it was going to let me. i am very comfused about this. if you have limewire and dont want people to download your files you should block it then, why would you report people for this? is it the person who has the file reporting people or is someone else doing this. can someone help explain this to me? i have used p2p programs for years and never had this problem before.
