It's never fun to get downvoted by a whale, but at least you're handling it in stride. While neither of us are the type of people to downvote others unless it's due to obvious spam, we're also not the type of people to downvote "just because" we can. If I were a less-forgiving person, I would downvote that whale's posts for a while just out of principle; although my DV would have minimal impact, not even a whale wants to see a DV in his (her?) notifications.

Did the whale "fat-finger" the DV on a mobile device or on a computer as a result of losing control of the mouse? That's always possible, and I'm willing to accept that reason if I believe it to be true. Many times, if this is the case, the DV gets neutralized by an upvote from the same voter.

For now, we just wipe the dust off our sandals and shoulders and move on to more pressing matters.
