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.
Now tell me how he "fucked over other people". It slowed down node processing of blocks. It wasn't even that slow. I remember CH/RS even boasted (don't remember forum or IRC) that even with this slow down, solidcoin is still confirming much faster than bitcoins. Sure, it crashed a few nodes due to the unintended transaction log growth. But this problem was quickly worked around by deleting the log files. All ArtForz did was to prove his point. Remember, his action did not cause the price of solidcoin to plummet. The price of solidcoin plummeted because CH/RS made a dick move to change the open source license. That was what "fucked over other people".
So ArtForz got shit on by CH/RS, and he performed a small attack to prove his point. Then CH/RS retaliated and pissed off everyone. I think what I heard recently on IRC summed this up perfectly: "don't piss on the heads of the giants whose shoulders you stand on"
