Gold buying problem

i bought gold from MMOOK a few times and the items i buy disappears the next day as well as the gold, by gamigo (unless i put in bianca), apparently if i buy again all my accounts from my IP address will be banned, how can i buy more without them knowing and not get banned

Try to buy items from player in black market maybe they are scamming u but i heard not often about problems after the trade with gamigo
