So, that's the issue for me and others with respect to multipool. Multipool was reaching "my" limit of unreasonable behavior for the size of the hashrate. In a manufacturing operation, you expect a mean performance and you have upper and lower control / spec limits. if you are drifting far from the mean, consistently, you investigate why.
Problem is that this was not particularly bad luck. You can't call it consistent either, because they mined for a very short time.
Complaints started when their mining was at a CDF of about 70% which is just silly.
Even at 95% CDF you may think this is really rare, but it's not. If you crashed your car 1 out of 20 times you drove, would you still say that's so rare you would never expect it to happen?
Fair enough, your tolerance for bad "luck" may be higher than mine... and you set the rules.
But in fairness, there are no safeguards against "bad actors" ... and there should be a definition for behaving badly (or statistically improbabe).
MP left ... taking 75BTC more than contributed... and we never got to see if he would have normalized
