Haejin does upvote for people. Apparently just not you! Exactly what have you contributed to the discussion? On Steemit, all have to EARN the right to request for upvotes.

He did spend voting power by upvoting commenters and followers during troll attacks.

I've reviewed your voting history...not a single upvote for anyone on haejin's blog...so what's your point? All followers in Haejin's blog help out each other but I don't see the evidence of you doing the same when we get troll downvotes. Where are you during those times?
