Why is @haejin's posts being downvoted again and Who is @Kimjongpoo ?

If you are following @haejin and have read the comments then you must know him, @kimjongpoo. He is downvoting every positive comment about @haejin. With just 11 followers and 47 reputation he looks like another bot hater of @haejin.

His profile looks like this

He says he will poo on us and is doing something like this. Recently @haejin post is getting downvoted by @randowhale and other bots. Why is it happening? Has @haejin broke the rules or they are jealous of @haejin?

We have seen in recent days @haejin is not powering up his post and this will break the rules @haejin and @berniesanders made. This drama is continuing and @haejin is the one who seems to be greedy but I may be right or there may be a complete different story for it but I think @haejin must have acted according to the rules.

But @kimjongpoo downvoting comments is not good at all for the steemit community and the overall growth of steemit.
