The problem with that is that it introduces a grey area. Right now, the rules are very clear and easy to follow for ninjas-- see a gamer tag mentioned that doesn't belong to the person who posted it, and it gets taken down. If you change the rules, the ninja then has to make a judgement on the validity and weight of the evidence provided- Is he actually cheating, or is this really just naming and shaming? Given that ninjas aren't bungie employees, and that they largely work independently from each other, opening up that sort of ambiguity is asking for trouble. If we had professional moderators or closely coordinated volunteer ones, that might work. As is, though, I don't see how it could.
