What does HackerNews think of profile?

https://github.com/settings/profile

``` Contributions & Activity

Make profile private and hide activity

Enabling this will hide your contributions and activity from your GitHub profile and from social features like followers, stars, feeds, leaderboards and releases.

Include private contributions on my profile

Your contribution graph, achievements, and activity overview will show your private contributions without revealing any repository or organization information. Read more. ```

I just get 500 on the homepage, and my profile also 500s when logged out. Most other things still seem to work, including https://github.com/settings/profile where I could turn it off.
If you're trying to avoid making your email public via GitHub, you should also ensure:

1) "Public email" is set to "Don't show my email address" under https://github.com/settings/profile

2) "Keep my email address private" is checked under https://github.com/settings/emails

It's frustrating that these are still two separate options - worse still that I believe I had the first option set when the second was added, unchecked by default, resulting in me leaking my email about a year ago. The spambots had it anyways, so I guess it wasn't that big a deal... and hey, maybe they added a warning someplace like I suggested?

Is the fix to go to https://github.com/settings/profile and put an email in the field labeled "Email (will be public)" ?

How does Coderwall allow github signups without me sacrificing an email to the public?
