TradeFortress is doing everyone a favor, showing how you can be ripped off or stiffed in an easy way. This could be a loop hole to allow Ripple to take your money and keep it and label it fraud.
TradeFortress is a reputable member of the forum for what seems to a long time, he puts more into Crypto than most. Im sure he has no need to take your money or SCAM you.
I would trust TradeFortress, with my wallet and kids.
