In my opinion more voting options in general are needed, regardless of the combination of solutions the community chooses to implement:
-
Abstain to make sure people who don’t feel they are informed enough and don’t want to delegate their vote can still get rewards
-
Spam so that malicious proposals can be more easily detected, filtered and deleted, for instance with Proposal to restrict rewards qualification to a threshold proposals without enough Yes votes would be less visible and that shouldn’t be the case, there should be a distinction between “I don’t support this” and “this is spam”. With a spam option it could also become possible to charge the rejection fee only if the proposal is considered as spam, incentivizing more people to participate in governance without fear of losing tokens, this would promote more named neurons submissions and a more active governance process.
The NNS is the best tool we have to gather the community’s consensus, being able to use it even for apparently disliked proposals will give us a better idea on how much stakers actually support or dislike a proposal.
