@nogajun That particular page does not show the mentions of dev comments or page links. It can be found, but not by me while preparing for sleep. It is enough for me to know this feature DOES NOT work to secure messages, as clients connecting to my server are warned, and I wish it did work. I'm using GeyserMC which requires this to be set false for that plugin to work.
That said, you are fear mongering over steps taken to prevent clear and obvious harm in violation of the terms of service. If your intent is to cause harm, pick another game.
