Someone threatening to ban me

Hello, I'm new to WoW and I just did my first dungeon without knowing the rules and fought fearsomely. Somewhat near the end I got the option to throw dice to get some shield, so I did that. Then the party members said I was a ninja and that they'll ban me. I tried to find it in my Inventory but it wasn't there, my Inventory was full. Then they kicked me and said I will be Ip banned forever. I really hope I Won't get banned because I'm really beginning to like the game and server and I have already invested some money.

Please help

You don't get permanent bans for ninja. If you didn't ninja, you won't be banned. GMs investigate the case, they don't just take the word for granted when someone accuses.
