i think its jealousy plain and simple. Haejin draws alot of followers (and deservedly so) and I guess other posters here feel he takes from their potential profits. They attack the commenters too in an effort to drive people away. I had the most upvoted comment on his post a few days ago and now its so downvoted its hidden and full of spam bot messages. The level of composure haejin manages to keep is pretty impressive because these trolls live to destroy his steemit
