Lol, no, come on! When have I ever put anything negative on chain :D
But seriously, I remember a few times were I wanted to decline rewards of a post of mine but eventually didn’t since it greatly reduces the exposure one can get by removing the incentive for curators to vote. For this, the solution you are proposing here appears to me as a better alternative. In the long run, to see decent adoption you will probably need to have it integrated as a frontend-solution though.
