 Wise to assume everything is an attack until proved otherwise.  Let's keep thinking adversarially.  Thanks!  Luckily, I think this one is only 5 blocks. 
 I see the "it's prunable so it's okay" argument all the time. People don't realize that we NEED full nodes that aren't pruned.... if majority of nodes get pruned the network will eventually die.  
 Yep, thanks for presenting a good argument.  That's the only way we can make bitcoin the best it can be.  More civil on nostr than on X!  I'm generally strongly against spamming the blockchain, especially with assinine inscriptions  I view OP_RETURNs as a more nuanced thing.  I was orginally against OP_RETURN when everyone else was for them, until they justify a use case.  Names on bitcoin might be that use case.  I can see utility in my applications, let's say I want to eliminate spammers and give users their preferred name, an OP_RETURN can give a (nostr) user proof of existence, and some skin in the game.  I remain open to facts and logic.  Thanks! 
 You don’t need the btc blockchain for this. Encryption, alone, is enough. This is why nostr works without any kind of dependency. This is a total scam.
