@contrasocial @ApostateEnglishman @majorlinux @atomicpoet I would say it's more the very concept of social media itself that makes that possible. A channel through which anyone can spread any lie they want to a bunch of idiots. Who can meanwhile lock themselves into bubbles surviving on falsehood after falsehood.
This is a bad idea. Look at a random day of things trending on Mastodon and how much of it is factually wrong.
That's probably a bigger risk than privacy (but people should do better)
