I taught Stat at Cal Poly during my university days, and indeed you get LOTS of false conclusions on these boards based on emotion instead of mathematical rigor. Funny at first, then tiring, then irritating - especially when coming from longtime members who should know better... 
I'd hate to know how high kanosan's aggrivation level gets sometimes with all the noob du jours chiming in during a run of bad luck!

It's a nice level of rigor to hold in a pristine environment. However, in the presence of enemy action there are no coincidences. You wouldn't last long as an officer.
Consider that at current prices $3.6 billion dollar of bitcoin will be mined. 1% of that is $36 million. Do you think people would fight tooth and nail over 36 million dollars? It simply cannot be assumed that you are not exposed to people with malicious intent. By the time you can confidently say using statistics that something is wrong the game will be over. This is the real reason no sane pool operator runs PPS.
That said, I expect Kano is just having a run of shitty luck. In his shoes I would be considering what an enemy might be doing, and how to detect it just in case.
There are limits to a sizeable sample of stats that say there is a problem, but we aren't at those limits yet.
But yes I'm already also checking things you can't check at the pool ... since I have contact with many of the large miners.
