There should always be miners selfish enough to mine any transaction. Isn't it?
How do you get every single miner to collude not to do it?
Miners don't give a fuck. They'll include anything that has high enough bribe for them.
As it should be. If crypto isn't censorship-resistant it's a toy. What has to happen to block the fork? Anything miners or nodes can do to stop it?
But it is vitaliks centrally planned toy. Vitalik has been and will be the central weak link of the project. If he wishes to break the immutability of the blockchain. Let it be so!
