I dont' know if writing more about the problem and showing possible solutions to the problem is going to SOLVE the problem. What I see now on the trending page is THE PROBLEM making $800 per post. NOW there's profit to be made from the PROBLEM existing.
He/they HAEJIN isn't going to suddenly stop doing what he/they are doing because somebody wrote a 1k word essay about how good it would be if he/they DO A). B). or C). Why would he? He found a flaw in the system and profit from it till it bleeds dry.
Those open letters are more invite to WRITE about the problem and push the post to the top of trending on the way $1,000 in rewards. Unless there's some miracle update (hint HF20) that prevents such abuses, HAEJIN, won't stop.
What would I propose? I say let the flagging continue, not because I think it's the best way, but because for now, it is the only way. In the meantime, maybe people should be supporting initiatives like @travelfeed that curates and supports authors who produce good content.
Wow, you comment makes a lot of sense, thanks a lot and I wish you a blessed weekend.
