It can be annoying but you can just walk away and go to any crafting station to access your bank. Actually I suggest doing this to avoid overcrowding around the bank NPC.
By the way though, I’m afraid blacklisting (specifying a player name in a negative contest) is forbidden on the forums. If you need to report a player, use the in-game function or a support ticket.
Whether something is either wrong or right, someone will always complain about it.
