Myeah declining rewards is just a bad idea all in all for authors who get autovotes cause you're basically just nulling their returns, but I guess you meant forfeiting them through beneficiaries. That's also why I would've liked the cross-post idea to be improved as it declines rewards on the cross-post.
I guess this idea just really makes sure there's no funny business attempts by farmers/autovote receivers who'll try and use the community idea as a reason to shitpost daily and accept all the rewards.
