But seems like you forgot all the dupes before jsp was even created.
Most items get traded on jsp so it’s not a surprise that you find duper trading there to. Also jsp has a scammer accusation section which you won’t find for any ingame trade. So you will never know how many items disappear from that.
Nobody cares about your click bait videos.
