But why would he/she have to? That's literally the opposite of innocent until proven guilty. The rules of steemit isn't, hey, join this community but also you are obligated to defend yourself from any and all attacks and explain all your votes and content to the satisfaction of everyone. That's...super restrictive and controlling. Not to mention like I said, there are probably users on here who are just for the "buy and hold in case this because the next Facebook in 5 years" and care very little about interacting with steemit beyond that. If that's true, why should they be dragged out and accused and forced to interact?

I wonder how long he would have continued to reward haejin had the community not said anything?

Who cares? Why shouldn't he? It's his upvote. He literally paid into this platform, and steemit rewards him for that.

I think people came to steemit with an idea of a very fair, even playing ground and 100% meritocracy. But that is simply not true - you can buy steem, you can buy SP, and the platform rewards you for that. I'm not saying if it's good or bad, but I'm just saying that's literally how steemit is built.
