I don't usually step into these discussions where I don't have anything of value to add, except to make smart ass remarks and take a shot at sarcasm, but c'mon guys, what's with this call to violence? You begin to sound just like the government: we can't outsmart them or we simply don't bother to try at all, so what else can we do? Oh, right, BOMB THEM.
I'm not here to judge, nor do I have the moral to do it, but just my 2 bitcents here, can we not create a honeypot scenario and scam the scammers? I know there's a test network

So here's what I propose:
- Lets come up with a legit looking exchange
- Get some bogus volume going
- Get the money stolen by the scammers on our pockets, along with the credit card details so we can give it back
- Log ips, try to get into their machines, etc
I can code something up, if there's people up for the design part. Also, we need to find a way to keep legit users at bay. Ah, yes, and there's no telling if mtgox and johnyrich didn't do that already... hehe
