Within the past two days, I've received 4 downvotes, one of which was from today. As the one today was on an answer that was a near duplicate of another answer, I have a slight feeling that I am being targeted,

as the MPW's answer received no downvotes, I don't think there's anything fundamentally wrong with my answer, and I don't believe the downvote came from MPW. Of course, this could be a false alarm, but it does raise my eyebrow.

The 2 of the other 3 downvotes came from some of my more upvoted things and the last is likely no targeting. Whomever downvoted this answer likely downvoted all of the other answers.
