re: Announcing the Oliphant Social BlocklistS (plural!)
If you want my opinion... instead of blindly basing blocks on how popular a block is, start with receipts... **require** any block on any list to have a receipt.. start a universal receipts system (I wrote one already, havent released, happy to team up).
That alone will eliminate the vast majority of the issue.. users can, as you say, actually validate against receipts, and the accused should (if the receipt system is open) be guaranteed the ability to provide counter-receipts, true transparency
