The smooth.witness account copies the votes from the smooth account. I could undo that manually but it adds about 15% of the vote weight of my primary account, so it isn't a big difference either way.
I will also be flagging this post for the same reason.
I'm open to upvoting to remove the bad reputation on any of these accounts but they will need to make a separate post or comment for that purpose, since changing votes does not change rep.
I'm not a fan of the reputation system generally and I have commented on the problems with it. However, I'm also not a fan of buying votes and the only recourse I have against what I (and many other large stakeholders) see as a serious form of abuse is downvoting the post. Unfortunately that automatically affects the reputation as well.
