Point is, if Alice and Charlie both behave exactly the same, both notice Bob does something bad, like calling in bid bots on a post tagged for one of the top curation initiatives (something I've used flags for myself a couple of times, and have been retaliated against a couple of times as well), and Alice was the only one acting on it by attenuating the bot votes with a down vote, then behaving like Charlie is incentified above Behaving like Alice by the retaliation by Bob.

For the flagging to truly work without negative incentives, I think we would need some kind of flagging SP that can be delegated separately from regular SP to semi-automated services. Without something that can shield those who for example want to use their free downvotes for attenuating false curation bot upvotes against direct retaliation. As the EIP comes with nothing that shields us from retribution down votes, I'm afraid the incentive to act is still negative.
