Nostalrius Begins - Quality wow vanilla realm (1.12)

Dear GM Team,

Characters are on the PVP server.

My bank account character (chrisqueline) was banned, which has been used for more than 2 months to hold the herbs, gold, runecloth and leather gathered by my main account character (Qoma). My bank character is a lvl 5 mage and has been staying at this level since 2 months ago and never left the StromWind City after she got there. Many people create bank char to receive stuffs from main character to save the bank/bag space for main character. this character will sell some stuffs on AH for gold for my main account character future use, never sell anything for real money. I am wondering is this not allowed on this server? Hope I can get a clear reply then I will not make the same mistake if I have to do the re-level things...

My main character and bank character have been on each other's friend list for months and all the mailing activities between them are constant and nornal behavior as being main acc and bank acc relationship. I am here ask for a further investigation and hope my accounts can be unbanned.

Best Regards!

Dear GM Team,

Can I get a direct and clear answer that is it allowed on Nostalrius server that one people create multiple accounts and mailing stuffs bewteen them. As mentioned many people create low level bank account character to hold materials from 60 lvl main character to save its bank/bag space. Is this forbidden here? I am already preparing the releveling but would like to make myself clear about this to avoid the same mistake.

Best Regards!
