This aren't anything new. How come you still fall for this youtube scam? People have been warning each other for years about those scams. Even few months ago, there was this twitter scam that used the same strategy to scam people and it made it to the headlines. I am sure you invested or sent money over there with a hope of getting back 3x or 4x your amount, right? Don't you understand that those offers are too good to be true?
So is there hope? Have other coins had coordinated scam site attacks with that duration and if yes how did they manage to contain it?
Scams like this existed for centuries. You can't "contain" it. All you have to do is be smart and don't fall for stupid offers/stuffs.
