Nostalrius Begins - Quality wow vanilla realm (1.12)

Hey, I think one of my friend was wrongfully banned today. He got banned while leveling his mage flybrother.
The ban may have been caused by his friend giving him some money to buy a staff. I'm sorry if that caused any issues. Please help us and check the reason for that account banned,thanks a lot!
