One thing is filing a complaint, another is accusing a company of being a ponzi, and randomly trashing its reputation when no harm was done; and even worse - non customers randomly trashing a business around and ruining its reputation - thats sabotage.
Keep doing what you are doing and you will end up with a self fulfilling prophecy, roaming around forums and posting false acusations on a business will destroy its reputation and scare away customers, and this will ultimatelly kill the business, it dies and yes if it died it must be a scam... sheesh
Good. Cloud mining services that refuse to provide evidence of legitimacy deserve to die. If they were legitimate though, they'd still be able to pay their customers and wouldn't even consider running away with the money. They'd also be able to refute the false allegations.
