if you are wanting to pay via card the best way to do that without allowing accounts to be linked is via amazon, in terms of bonds I tend to withdraw gp from a site like bbb onto the acc then just running it to ge to buy a bond, so if you have a way to transfer to to the acc via a 3rd party thats abit safer for your main however I have never had one of the accs iv used in the past to bond accs banned unless it recieves items off the bots
