I think those are only rumors.  I have been looking through as much as is publicly available, and I would find it very surprising if they were indeed in bed together.  They probably tried at one point to join "forces" (I cringe writing that word), but I don't think anything came out of it.  We would have heard and read something.

HOWEVER, if indeed there are some accusations that justifiably stick, and even perhaps finally some criminal procedures, doesn't that create a precedent that would allow us (I wonder who this "us" is now) to inexpensively file a complaint that would finally go somewhere?  There won't be "more" cash for any of us creditors, but it would fit into Miner Minor's wishes since he said he cared more about revenge than actual cash back.

On that note, were Hashfast's books ever reconciled properly?  Why is it that I remember it not being so and there being still many bitcoins unaccounted for?
