If the hashing power was provided by AM.
And the management by RockMiner.
How do you know RockMiner was not the cause of the loss of equipment that they were managing for AM.
Because in that case, I dont see AM would be responsible.
It does not matter really who is responsible. AM is broke and so is RM...the ponzi has fallen apart and is over. No one is getting any GH or coins back.
