I know you're not supposed to post about this, but I'm kind of curious if there is a particular user on HN that seems to have a grudge against my posts? Until recently, I have never gotten downvotes, and now it seems that I consistently get one on everything I post. The tone and style of my posts has not changed over the past year, so if I have somehow upset some user who is now revenge downvoting, I apologize.
