Today I saw a user in a per site meta that has a reputation tab like this:

Their meta post is about something else though. The problem I have is with this very screenshot:
4 un-upvotes took place in a range of 5 minutes

For the sake of a consensus, I'm not asking for someone to look into the particular case, but I'm asking if there's a new (?) phenomenon we should be wary of: Serial un-upvoting

There are two opposing views:

• Every person has the right to vote and undo their vote. This isn't something to worry about.
• There's no reason for us not to deal with this like we deal with vandalism et cetera: What if the destructive behavior the user chose was to unupvote useful answers? The post score isn't for decoration; the usefulness of the voting system relies on the maxim of vote on the content, not the person.

So how should we deal with a case of "serial un-upvoting", if we do consider it unacceptable behavior?
