Ya bitcoin is equally suspect for the same thing. But solidcoin is turning it's efforts toward patching much of the security flaws from Bitcoin so that further attacks from bitcoin community members are much less likely. Bitcoin is really earning a name for itself being the currency of choice for money launderers, drug addicts and black market, malicious hackers and scammers....
The flaw ArtForz used isn't actually a practical attack against Bitcoin. But nice to know you're still valuing the SolidCoins you have enough to be willing to spread lies to make SolidCoin look good.
