Interesting, but that makes me think of one thing. If tomorrow I create an account to mess up Steem, that I manage to reach -18 by reputation, all Steemians hate me and with this false account I send some SBD or Steem to someone influential on Steem via his Bittrex ID, or to you for example. Everyone would think that the owner of the Bittrex ID would be responsible and all this for a handful of dollars. I personally find that dangerous.
