Being karmassassinated wasn't something I was expecting, certainly; I don't recall being unusually controversial beforehand. In fact, I hadn't logged in for the past few days. But I was, statistically, probably arguing with around three people at the time.

I wouldn't want to hazard a guess as to the precise individual, though; it's quite possible someone's just been increasingly annoyed at me without saying anything and finally decided I had to be taught a lesson. (Good luck with that, culprit, if you're reading this; anonymous downvotes are not the most efficient means of communication.)
