You've clearly missed some of the drama. Another user, BernieSanders, led a campaign to downvote Haejin. It's still going on, with tons of Haejin's posts being hidden. Meanwhile BernieSanders was downvoted by others and he dropped from somewhere in the high 60s down to level -18.

GrumpyCat is campaigning to prevent bots from voting for posts that are more than 3.5 days old. He's been downvoting tons of bot-upvoted posts for weeks.

There's a lot of people abusing the system. There's also a lot of people trying to fix it. I haven't lost hope, rather I'm trying to contribute, to raise awareness, and to help where I can.
