I made this post (https://steemit.com/steem/@gridcoinman/what-do-you-think-of-my-steem-power-3d-model) a few hours ago, within a few seconds of posting it received about 20-30 votes almost simultaneously. All the accounts are brand new with less than 10 steem power and no posting history. Anyone care to explain?? I was under the impression the new fork prevented this type of behavior.
