I have an Xbox 360, one day the slipknot band showed up in my friends rankings in spite of the fact none of my friends play RB3. I noticed that every score I got in my band, the slipknot band got in theirs, identical scores, with identical instruments. I tested it out last night with a random song and purposely had the guitar laying off to the side with no one playing it , and totally freestyled on drums. I got 2 stars on the song 0% on guitar and like 50% on pro drums and they got exactly the same score as I just got. This needs to be fixed because it is either just an annoying bug, or somebody has intentionally hacked the server to piggy back off of other peoples scores.
