[Answered] How to gain 1 karma point

Hello everyone, I'd like to get 1 karma point so that I would have 2 karma points in total, so that I can prove my HackerNews account into my Keybase account. Unfortunately I have no idea how can I gain karma, since I haven't used HackerNews that much.

Can someone help me understand how I can get that 1 needed karma point so that I could prove my identity?

Edit: My intention is/was not to "whore karma points", I just wanted an answer on how to get karma points, since I didn't know how it works and now I know that upvotes gives karma points. Please don't upvote anymore, I don't want to get any more points, I only needed 1 more point (which I already received) in order to claim this account for my use in Keybase.
