The question in question is this: SSHing firstname.lastname@example.org shows wrong/old SSH key.
I had assumed wrongly that the SSH key fingerprint displayed when you're SSHing into GitHub for example, should match your own Public RSA key. After reading the answers, I realized it was simply GitHub's own Public key's fingerprint (so as to authenticate the host you're trying to connect to).
Since the question is wrongly framed, I can't really accept any answer (which would lower my accept-percentage BTW, so it's not like I don't want to give away reputation). I can't delete it either as it says "Sorry, this question has one more answers; flag it for moderator attention instead", even though its my question; I guess this is because, as it says in How can I delete my own question with a low score but with answers? I'd have wasted reader's time.
I don't want to lose reputation, nor do I want to turn Stack Overflow into a big pile of junk.
What should I do, without losing reputation (if possible)?
