I'm looking at the sign-up process for Reddit now, and it seems to have a "Continue with Apple", "Continue with Google" and "Continue with e-mail" options. Even with Apple's e-mail obfuscation, there's still an e-mail associated with newer accounts, I think.

If you don't verify your email a lot of the site is unavailable to you. This is not disclosed on sign up.

They suspended my account, reactivated it and then suspended it again for not having an associated email address.

Same for me and my account is >5 years old and never had any problems.

I've never verified an email on reddit (or even provided one) and I haven't noticed any issues. What do you lose access to?

"Quarantined" (wrongthink) subs and I think NSFW ones. Probably more now as they continue to trend toward MiniTrue.

Ah, quarantined might be true. I'm on some NSFW subs without verification though.

As of now you can still access NSFW content on old.reddit without needing to be logged in.

Things like mailinator work for reddit sign ups.

IP address, DMs, probably lots more.

I requested my GDPR data and they didn't have much data on me - not even stuff such as links that I've viewed in the past. The most private information is a history of IP addresses that I've logged in with recently and the IP address I registered the account with.
