Maybe this is just a symptom of my screen addiction, but I keep a close eye on this site for a lot of the day. I’ve noticed a pattern where my commments initially get one or two upvotes (within the first 5-10 minutes of posting) but will then immediately get a greater than or equal amount of downvotes very quickly. It happens consistently enough that I’ve noticed a pattern. The upvotes happen sporadically and the downvotes happen simultaneously.
