I recommend instead of trading your gold to your mule try to drop the gold on a table in a world somewhere where theres no one but you in the area wait like 2 mins for it to pop up on your mule account then take it as jagex has no way of keeping track of gold that has been dropped onto tables sorta like bitcoin except for osrs haha. thing is if you do trade your gold like through jagex can see that you traded and will ban that account for association with the other banned account.
