This idea couldn't be more simple. P.T.S works like an invite and CAN be ignored. As soon as two people enter a trade, the two people gain invisibility and invincibility for the duration and five seconds after the trade. The system will work like the tables but free and with less slots. This way has less evidence (Unless you were recording) of scammers as this is a thing that happens in a window instead. Trading will also need a cooldown (1Min) to let the original trade tables rival the P.T.S and not be overpowered. This system should also come with the update of trading hats and enable selling for some items that aren't. This is my idea for the P.T.S.
