Thank you for the feedback @Omaxus !
With respect to spam due to a financial incentive:
- Post the automation of exchange rate proposals, 10 ICP is probably not good enough for a spam prevention with respect to financial incentives. See further analysis here.
- This proposal by @skilesare which was approved in the meantime entirely removes the financial incentives for spam.
With respect to spam for other reasons
- I agree that your proposal could be used in that context. And as you said, it would be more a mechanism to reward good behaviour.
- In addition we would still need to conclude what further mechanisms for spam prevention we would need (in case that 10 ICP might not be sufficient)
