> They do (and any service basically). You don't want to run a large-scale service without having some way for your users to self-reset their passwords.

I don't buy that. There are other similar services that allow an email address to optionally be provided later, for password-resetting purposes. I believe reddit is like that, as is this site.

This site gives me a "Please put a valid address in the email field, or we won't be able to send you a new password if you forget yours." message when I view my preferences, for example.

I don't buy your phone number claim, either. There are many other services out there, including ones that very likely have a presence in a country like Germany, that support user-posted content but that don't require a phone number to sign up.

Anon users are the worst part of twitter. They should be completely banned. HN doesn't have this problem because it's sufficiently niche, but the Nazi trolls and other assorted idiots have to be dealt with on twitter.
