Nobody can kick you off #nostr for posting "bring back the guillotine", it's still a dumb and irresponsible thing to say. Please think about what that means, calling for the public beheading of a specific person. Even if you say it as a joke, how many will read it unironically.

I recently read Joe Abercrombie's "The Age of Madness", which plays out a kind of French revolution in the fictional world of the "First Law" trilogy. Excellent and terrifying read, no guillotines but an equally grisly method
