>>10984333I'm supposing it was random. This occurred on one of the faster moving boards, so that lends some credence to the theory. However, while I have zero idea what goes on behind the scenes at 4chan, I'm sure the mods could artificially do this. I just can't imagine why they'd want to.
As an aside, if no one can answer my original question, I'll be seriously disappointed in this board. Seems like a fairly simple conditional probability question. I'm just not any good with math.
