Copyright on Commons is a topic that is at times, subject to abuse. Some images are left for long periods of time because people are afraid to tag them, and other times images are subject to the copyright whims of admins. It would be helpful if there were tools to both help detect possible violations (there are perhaps databases we can match things up against?) and a better method for screening images once detected.
