Yes, I think I get this. In fact, in order to *filter* something, you have to *look for it* My node sees a provably unspendable op_return output from a TX and depending on the threshold, currently 83 ...
I agree. Intent matters. In the analogy you presented, the Core node wouldnt kick the person our of their house. They would take a picture of it on their phone so they have a copy and send it to their neighbors. And if somebody won the town raffle, the image would get displayed at townhall forever (blockchain). Sorry, I kinda had fun with that lol
