If there was not a demand for the information that Haejin posted, it would disappear into the void and be about as irrelevant on this platform as you. But since he brings value, he accrues value. Perhaps spend less time trolling, and create content that add's value. Better yet, if you dislike Haejin so much, unfollow him, and forget about him forever. Live your life Haejin free. Or at least bring an intellectual conversation to the table. Otherwise you will never be happy mate. Life as a troll, worrying about others will surely get old.
