I personally would rather devote my puny upvotes to the guy who is actually creating something than to somebody who is only rewarding himself and cynically exploiting the way the system works.
That's what it comes down to for me as well. I see a lot of great work on this platform that struggles to get rewarded, and it's frustrating to see the potential of abuse. Again, I don't know if @haejin is truly gaming the system, but I do think that the evidence points to that being a strong possibility, which is concerning to me.
