Yes. I see this is a problem. In 1930's Germany these kind of referendums(fraudulent?) made the world-wide catastrophe.

Anyway it is fundamentally(?) always the majority who agrees on the rules. And the majority chooses how to advocate for minorities (one of which could be a terrorist organization).

So in case there are bloody coins on the blockchain - the majority has two options:

- collaborate with terrorists (do nothing)

- freeze the coins
