And as I've stated in response many times, and nobody has addressed, the big difference is that by voting on content, stake is decentralized because half goes to the authors, while in this case y'all are able to maintain your 50% curation, AND keep the rest by sending it all to the "fund," where just a couple accounts (the ones upvoting these spam comments) decide how it's rewarded.
It's just self-voting with extra steps.
RE: The main excuse for malicious down-voting is "Over-Rewarded Content..." What about the account making $10k+ PER DAY in spam comments?
