To reward these activities under “Defending cases”, we would need a clear way of measuring each of these actions, and decide how much to incentivize each action. Vouching is a lot easier to measure than those, since the actions occur on-chain.
I invite you to check this idea that might allow for more flexibility and nuanced rewards for each action: Brainstorming Appeal DAO Also, such DAO could ask for a grant from the PoH DAO.
Similar to the above, if all crowdfunders in the platform are incentivized, then someone that actually has the funds will have an incentive to have someone else crowdfund them, and then crowdfund someone else with no actual benefit to the registry.
If we consider that most people doing crowdfunds are not doing that, then it might be a lesser problem.
