An interesting side note of that is if the majority of miners voting decided to zap the wallets of all known nazis and white supremacists, they could do that too.
It's interesting to note that existing financial institutions can do this too. And in fact they do, if they suspect you are involved in a variety of criminal activity they can freeze your accounts and alert law enforcement.
However, those institutions are subject to the rule of law, and if you are wrongly treated you can expect restitution.
From my perspective, cryptocurrencies are a sort of wild wild west at the moment where the standard appears to be: if you are wrongly treated good luck!.
