I've had a comment to this recent question removed without, well, comment and I'm curious why. The deleted comment was: "(Incidentally, I disagree with the downvote and have upvoted to compensate.

(This actually happened multiple times, since at first I wasn't sure my comment had in fact gone through.)
Here's a screenshot of the comment thread pre-comment-deletion:
