I wonder how they could have determined all of this in two days and set up the coupon nonsense. Seems like that would have taken longer to do all this.

And, I think there is a way that we can look up on the blockchain to see if the network was jammed.

"We tried our best, did all that was humanly possible to discern between the genuine and fraudulent registrations considering that about 90% of the people who registered to our bounty campaign still doesn’t know what Ether is, not even today"

Contradicting statement. How can they determine that 90% of accounts are fraud and how do they know who knows and doesn't know what Ethereum is?
