Would reporting them to twitter get their account closed? As they are using it to scam.
And thus make it more difficult for them to raise money and repay us.
Here, I am somehow confused.
Why do you think that they are raising money? Let have look at website once more. Mining is practically non existent there when they could simply maintain pools or trading to have good portion of money raised from just fees. I was die-hard fan of coinex and would accept much higher fees if that would help to sort out things and I know there would be hundreds of people doing the same. But from how it looks, nobody is doing anything.
