There was one website, I think it was Facebook or Twitter (before Musk) that banned someone's account based on what they wrote in a private message.

It was a huge disaster, that most individual websites shut down and moved to Big Tech (Facebook, Reddit, Discord, etc.) I always cringe when someone says "Follow my game on Discord!", because they're promoting Discord and not their own website. Discord is user friendly right now, because they're in growth mode, but it's only a matter of time until they enshittify like everyone else.
