Firstly, there is no such thing as 'ninja' in WoW.
There may be scams, but no one can loot if the mechanics don't allow permission. To 'ninja' is to steal, you can't do that.
Secondly, Master Looter gives explicit permission to that person to do as they wish with loot. Now, if there ARE specific agreements made, that may be a 'scam'.
Lastly, Master Loot really isn't ideal for pugs. It's best to not use that loottype with people you are unfamiliar with.
If loot has been awarded in anything but a scam, the person in possession of the loot is the one that needs to submit the petition for a swap.
