What GitHub exposes about you: Name, Location, and more

The actionable take on this seems to be: "Why you should use a pseudonym on github, configure hiding your email and full name, and beware not to link to your social-media or other personal sites or information - if you choose to still be on Github".

How is this information leakage worse than (say) Discord though?

General advice seems to be to use pseudonyms in general online. (Then you have the reverse problem of not getting attributed with your code.)
