Yeah but my point is that it's not hard to make a bot that goes through the platform instead of directly interacting with the blockchain. If this were to go live, it would only take me about 2 hours to break the system and make a bot that simulates a human and that clicks. I would read the blockchain to see sbd payments coming, and then when it's time to vote I would open the web page and programmatically move the mouse on the platform to click.

Plus the issue is that then the rewards become platform specific, like there would need to be a central authority that can say "this platform is ok, we give more rewards, this one is not we give basic rewards", and if you don't want the central authority and any platform can have the "normal" reward, then I would make my own platform that automates voting.
