7. Public-facing social media platforms and identifiers/handles used during the last five years. This includes any websites or applications the applicant has used to create or share content (photos, videos, status updates, etc.) as part of a public profile.
I was advised by my lawyer that this covers Reddit and HN, and Facebook/Instagram (if I had any of those which I don't any more).
The lawyer didn't mention github however, but someone can search my name and find that in 1 click anyway, that's hardly private information.
