Given CoinHunter's egotistical behavior on the forums and on IRC, I can't fault ArtForz for attacking SolidCoin to try to put CoinHunter in his place.
That is such a shit argument for defending Art. I think it is safe to say that there are just two wrongs that have been made and so people don't have to pick sides. Art got shit on by CoinHunter, and instead of being a bigger person went on and fucked over other people based on one persons actions.
Or the alternative:
Art: Hey, here is an exploit, you should fix it
CH: Screw you fella!
***exploit remains active***
UNKNOWN: -attacks the chain even harder, causing a BIGGER issue-.
