Yes, but on the question is not if you WANT to store arbitrary data on a public wall. The question is if it is RIGHT to do so. The mature answer to that question is clearly a no. Graffiti has always existed and I’m not dumb enough to think you will stop, but I also am not going to stop shaming people for selfish immature behavior. Ideally we find a way to prevent it that doesn’t compromise the monetary use case of Bitcoin. In the meantime, all I can do is ask people who choose to do it, as nicely as I can, to please quit being assholes.
