Very good move by the coinbase team, but i wonder how they managed to figure this out that the receiver's address is for hackers or they where just being suspicious?
Because those tweets followed the same painfully obvious way of operating as all the other trillions of giveaway scams. This is makes it doubly flabbergasting that anyone would fall for it.
If I were running Coinbase I'd tell those fucking morons they weren't able to withdraw their coins until they'd passed an IQ test.
