I have been Banned for Ninja looting when I gave the item to the winner!!!

I need to speak with someone ASAP! I have been banned for "Ninja Looting" when I gave the item to the 2nd highest roller a rogue named Prosit! I respect the players and the rules! Ive played warmane for over 4 years and this has happened to me before. I don't understand why I am banned when I gave the item "Tarnished Elven Ring" to the 2nd highest roller because I mean't to greed but accidently pressed need! The item went to the person it was supposed to I still got Banned, I just don't understand. If I could speak with a GM as soon as possible I would appreciate it! Thank you!
