It's not really a scam, they're sharking. You are purchasing a legitimate contract, but without knowing it will not give you an ROI. They did not tell you you would get an ROI, but you think you will.
Marco's a mathematician. He knows what he's doing when he's building such contracts.
GM will survive from Ethereum mining for who knows how long unfortunately.
As long as Marco/GM-PR narrows the social interaction or feedback through BCT and FB. Complaints or public outcry can still be mitigated to ensure new investors won't know previous products don't work out. GM deletes most conflicting comments on youtube vids and other social media. Worse, your told to open a support ticket leading nowhere or given a proper explanation about mining difficulty and your payout/maintenance fee.
Additionally GM's PR utilizes prominent public figures to associate their brand name with them.
Do you think any of those people or their representative firms approved any of it?
When I saw the Stephen Colbert ad and knew what show they quoted him from.
It had me feeling like creating an ad depicting what I thought of Marco and GM.
I don't think Mr. Colbert would approve of his reputation being used by GM.
Unfortunately GM didn't want it on their main thread and it was deleted.
Along with three days worth of content.
Can't imagine why...
