I recently changed to a keybase profile only due to spam. However, thanks for pointing it out. Maybe it still creates too much friction. Folks can reach me via ck at firma dot de.
I’m confused and you are correct. Being logged-in I see my about section filled with data. If I open my profile as anonymous user with incognito mode I do not see any content. Not sure what’s happening. Thank you for pointing this out.
I saw a bunch of new accounts spamming their Keybase proof in all the wrong places. Maybe HN did something to combat the spam and it accidentally hit your account.
