I suspect this user was temporarily suspended as a result of some of my back-and-forth with him on this question. I'm not sure I would have asked for an outright temporary suspension–I had been hoping to resolve the situation "peacefully".
(It was also a fun opportunity to practice my Russian, and it amused the Russian-speakers around me.)
I didn't downvote his answer until it was clear he had no idea what I was trying to say and didn't feel a need to either (a) clarify his answer, or (b) ask the OP what the actual question was.
I have no problem believing he answered the intended question, I just don't think he answered the question as asked, and somehow that turned into me being a moron. (Which I don't dispute.)
I'd prefer him back, perhaps with a note stating that I (me, Dave) really don't know what his issue was or why he felt the need to attack me personally–I thought I was pretty reasonable. (Delta an lol or two.)
I'm not convinced he went so far to deserve suspension, unless there was other stuff I'm not aware of. And if there was, tell me, 'cuz I love stuff like that.
(Coincidentally, he and I got in to it again recently, but I hadn't realized it was the same user as several months ago. I guess it's more systemic than I had originally understood.)
