How so? You literally just open a web page, and choose a nickname. It's easier than creating a Discord account and verifying your email address and phone number.
Discord has a gradual onboarding process. If your IP isn't poisoned, and your browser looks pretty normal, you just have to enter a username and you're in with an "unclaimed account"
They'll then nag you to fill in more details as you use it. It's honestly a pretty slick way of doing onboarding.
