Scam for sure. I have a large website list with a similar script on them. Big promising, high return of investment. Here is the thread:

OP, little advice, add words like
scam, fraud, fake, deception... right next to the domain name in your post, just to be related in the search engine.
I was thinking, maybe it would be to get some comprehensive base with all websites which tried to scam people using doubler, cloud mining, Ponzi and etc... scripts. it is important that such information is available. can also be important for domain traders, who want to buy a domain name which is related to fraud in his history.
