.There is something that can be done about it, keep including @steem as the leader of the downvote bot army. If @steem withdrew it's delegation then at most the accounts would only have enough RC credits for the first free two down votes, then maybe on or two at most other down votes before they are out of Resource Credits. No RC's no actions can be taken by them. These accounts are not in compliance with the steem white paper, and they are certainly not members of the steemit communities. They are Troll Accounts that are being enabled by @steem. So keep mentioning @steem as the Enabler of these accounts then maybe, just maybe they will withdraw their delegation from this type of account.
