I would like to mention again, that this entire "Ninja in RDF" rule is incredibly inconsistent & undefined, and is more than often used to satisfy personal grudges than actually disciplinate people who ninja gear-upgrades. I'm not talking about getting banned over ninjaing a fos/pos/hor hc item. I'm talking about for example getting banned for need-rolling a blue trash boe that can sell for 300g+ on the AH. The hypocrisy in this rule, is that while everyone will tell you "don't click need even if it's just a green: it's ninja", I've not seen a single ban for Need-rolling a Wodins in ICC to sell it on the AH. Granted, you could argue "Raid-lootrules are the responsibility of whoever is leading the raid, but for RDF it's an independent system so no one can be held accountable". But using "Don't need-roll on anything if it's not an upgrade for you" is in my opinion a pathetic excuse for anything below Epic (aside from lower level twink-gear). For every malicious Ninja that got banned, you have 5 new forum threads of people who genuinely don't know why they got banned, simply because they were running on a different but innocent common sense. There is no leeway in this either, as the rule would rather have you let a valuable item get disenchanted, even if it would be worth 20x more in the AH.
If the rule is gonna stay as it is, then at least, if not for the sake of your playerbase, then for the sake of your ingoing GM Tickets, make the rule more transparent and defined instead of a single footnote in a thread that is about Raid-Ninja rules.
