It' s not the accounts that make the ninja mining, it' s the stake itself. If we want crypto investors to take the fork serious as a ninja-mining free chain, blacklisting a few accounts from an airdrop isn' t going to do the trick. The ninja-mined funds themselves will need to never have existed, and the way this could be done in a fork would be by constructing a defensible replay strategy, picking a defensible monetary rebase block, and then doing a rebase and replay as proposed above.

And yes, this would mean the airdrop might turn out meager for some and overly rich for others, as replayed upvotes done with ninja mined stake, exchange bought funds that the exchange could never have owned if it wasn' t for ninja mined stake being sold first, etc, but the stake after a replay will truly be free of ninja mining influences. An absolute must if you want keep yourself from forking over the reputation of being a ninja-mined shitcoin from day one.
