What if instead of incentivizing for engagement, we can incentivize the identification of spam 🤔.

Yes (memerel), at the same time HOP successfully incentivized their community to combat airdrop farmers so it can be done.

The fact that it's hard to implement doesn't mean it's impossible. But IMO it's not worth the effort because the current methods work pretty well
