I was able to use the CTRL-F (find) feature of my Chrome browser and on page 12 of your history, I found several "downvotes" on the "if 60 minutes..." post
I find it very interesting that they are all part of the same group that downvoted The Dollar Vigilante post a few days ago. Steemit should be able to rectify this. These accounts have been doing a lot of downvoting the day they hit your post, because they only had 47% Steem Power left available that day.
