The problem doesn’t even seem to be the hacking but how easy it is to gain access to a chat. I didn’t look into how the editor got invited but think of how easy it is to get a random number invited to a signal group chat. It doesn’t take much social engineering to slip a number in there with this chaotic oh no wait DISRUPTIVE administration. No authentication required. Just send a mail to xXshitlord2006Xx@doge.boys with the text “Oy bro, send group invite”

Billions of years of evolution leading to this. Tons of research with the same result. Nope, says narcissistic sociopath, you’re all wrong and I’m right.
