This is correct. I'm a UK Discord user, so I've been subject to these requirements for ~6 months now. It's basically nothing - I'm in near 50 "servers", of them all I only really can think of one channel in one of them that is flagged "nsfw" and thus blocked to me as I never ID'd myself.

If you don't use Discord as a source of "nsfw" content you can comfortably ignore these requirements. I do realize there are some communities that may fare a lot worse than my gaming / software dev interests, and may be falsely claimed "nsfw" just for their existence. Which yeah, that absolutely sucks.

Whether I have to provide ID myself or not, I prefer to live in a world where when a company even announces that they plan to do facial scanning, they lose most of their customers. Hard to keep track of everything every company is doing of course, but I will try to migrate off of Discord ASAP.
