That reminds me a lot of the treasure chests in low-level areas.
No bans resulted, just a funny memory.

I was on my Undead Warlock, clearing out some house in Tirisfal Glades, when I saw a treasure chest. Mind you, I was new (I still thought that other players saw the shining loot on my kills, so I looted as fast as I could without knowing how to auto-loot, I would actually panic when my inventory was full and I couldn't pick up a quest item).
So I did what any new player did, and freaked out about this chest. I ran up to it and tried to open it, but I was attacked.
Enter the Rogue.
So the Rogue gets a few seconds into opening MY chest, and HE gets attacked. It's now a race to open the chest, and my heart is racing.
I win.
I proudly loot a handful of copper, some cheese, a linen cloth, and a junk shield.
"I BAN U".
"What?"
"U STEEL MY BOX I BAN U MY FRIEND IS GM"
"I'm sorry, I was here first."
"5 GOLD"
"What?"
"GIVE ME 5 GOLD AND I WONT TELL MY GM FRIEND"
"I don't have 5 gold. You're welcome to this shield though." I then spend like two minutes trying to figure out how to trade this shield. I look back up, manual in hand, and the Rogue is dead."
"HOW U KILL ME?"
Then I found out I could right click portraits. Trade and ignore are so close together. . . Yeah, ignore sounds better.
