i think it's just been a bundle of problems cropping up including:
btct closing
pool having bad luck and thus switching pools
Well, again, Garr mentioned that he was mining solo... Which means that he can't provide any evidence that it was mining at all.
Most likely he just stopped giving a fuck about miners for a month or two.
I agree with Tafelpoot that it no longer makes sense to ask for explanations and demand compensation instead.
Garrett already demonstrated that he will go to great length to avoid accusations, so it's just a waste of time.
In any case, (no matter what actually happened) it was a mismanagement and we can demand compensation.
