Hive account@mack-bot's sole purpose right now is to provide a token or marker downvote on known farming accounts immediately after they publish a post or comment. Currently it is running locally on one of my desktops but I have leased a VPS that my bots and scripts will be moved to in the next few weeks to ensure they run smoothly with a 100% uptime.
Hive account@mack-bot is currently leaving comments in reply to both posts & comments that have been downvoted and will do so for the next 14 days. After that it will only downvote to prevent adding unnecessary spam to the block chain. I have over 14,500 accounts on my list and have found one or two that were false positives. I want to ensure that anyone who is downvoted and is not part of a farm can contact me to review their account and remove it from my list.
While the downvote has no real weight or effect on the the account reputation, post or comment it serves to identify active accounts. 
Hive account@spaminator will use this to follow up with a heavier downvote about 6 days after Hive account@mack-bot's downvote to remove any pending rewards.
All community projects and bots are encouraged to follow both 
Hive account@cheetah & Hive account@mack-bot votes. By adding code to your bots to check for a flag from either account before upvoting you can help stop these farms from profiting. 
Hive account@minnowbooster is the first community project to follow both bots.
