I've just become a victim of serial downvoting, or at least I believe so. Some posts of mine from years ago had been downvoted out of the blue, and more recent ones as well. Naturally, this decreases my and many other victims' reputations. Furthermore, I'm at risk of being autoblocked, since so many posts were downvoted.
Now, I'm confused. I haven't posted anything that might provoke anyone, as the latest post was fairly well received; in fact, several users have upvoted the post.
Moving on, I believe that the current method of serial downvote prevention is merely insufficient. Just having a single script (that sometimes doesn't work) look for serial downvoters is just not sufficient.
What would you think is a better solution?
