But what if that message if for the greater good of yours or the community as a whole? Messaging should be allowed on steemit. I am against on this 'transfer money while you talk through memo' thing. there are many things, some urgent as well, which need to be discussed. So, I guess there should be a message option with a block option so that you can block those who are spamming your message box.
