My comment on checksums was a overall comment of shoddy and embarrassing hacked crap they call Ethereum.
They claimed again and again that the code is the contract and vice versa. That was proven not true by the VIP() function.
And seriously, if this protocol was given proper due diligence, there would be no reentrant attack on this. But that points back to amateur hour. And a lot of people here have money in ETH and can't come to understand this due to the extreme cognitive dissonance.
(The premise of Ethereum really is amazing. Too bad it wasn't given the same diligence as Satoshi gave it.)
