Zuck probably doesn’t even know he’s here, but you can mute the account like any other nostr account 

 Just don’t want him on here period. 

 It doesn't matter what you want. That's the whole point of Nostr. 

 And the whole point of Nostr is that I can say whatever I want! 

 You absolutely can cry about someone using it while being able to do nothing about it. 100%. 

 I wouldn’t waste my time crying about it dude!
