You make a few very good point against the buying of votes. If we did not have self votes enabled, or the ability to make multiple accounts, I’d say there do be no need for further regulation, but since gaming the system is so easy and the wealth is not well distributed, I think that kind of system would help. I don’t agree with Haejins activity on the platform, but the same people demonizing him the most violently have enabled him through their own abuse of power, even if it is sometimes done with good intentions.
I’m not sure if removing bots would be possible without the company exerting a huge amount of control over the ecosystem, which I’m not sure I want. You are right though, the answer doesn’t lie in targeting individuals, it lies in a change in the culture and algorithms and a fairer distribution of wealth. But first these people need to see that there’s is a problem with the distribution.
