Selling an item as anonymous is logical because people can SMS you before purchasing the item in order to bargain. However, buying an item as anonymous is not logical because the purchase already has been made and there is no reason for a buyer to SMS you for asking you to buy more units or asking for money (aka begging), we have the /smsmute or even /ignore command for such cases. Players should use those commands to avoid such trivial cases instead of wasting administrations time to edit an already complicated GUI. Sorry but I do not support this suggestion.
