They aren't my post. They are some front page post that have no reason to be downvoted afaict. The only reason I can come up with is that someone wants them off the front page, perhaps for a screenshot for an advertisement. I don't know. I probably should have just left it alone. I have an issue noticing anomalies and tend to bring them up. ;)

yes, I have had this issue with some posts that I do not want to downvote but when I click upvote I see they were actually downvoted.. hence my name on your screenshot.

Well there's another reason. Perhaps this needs to be looked into if this many people are upvoting but their votes are being counted as downvotes. The conspiracy thickens! ;)
