you're looking at a downvote from an account with a 25 reputation, about 15 (typically delegated) SP,

All these accounts are powered by @steem. He is the one that has delegated to the accounts. Some of these accounts set witnesses, and recieve 0.001 steem in the wallets, which is transfered to @camillesteemer that account now has 90.876SP. If you look at the incoming transfers, (two of them yesterday), he is still receiving those tiny witness/resteem bot wallet donations.

To solve the issue is simple, @steem needs to remove the delegations from the accounts that do nothing but down vote. So in a sense @steem is the Commanding General/Financier of the Army of down vote bots, and @camillesteemer is the president/king/queen/emperor or what ever you want to call it.
