The account balance of the botnet has been donated to Bitcoin Faucet.
While I enjoy the "revenge" and "justice" of denying them their money, I think that legally, it was not the proper thing to do. Courts decide how to award damages, not site owners.
No, the Mining Pool owners decide how to award coins. If you don't like it, mine with another Pool, this is not a legal arrangement.
I for one agree that BotNets mining against pools are illegitimate users and anything can be done to their proceeds.
However, I would have donated them to the pool operators, since they're expending costs just to fix what the botnet is NOW doing to them.
I have to agree with you Rob, it's unfortunate that BTC Guild has to pay for the bandwidth consumed by the zombies. I would create a form letter notifying the individual ISP's that are providing bandwidth to the zombies, and blast it out to the relevant ISP's abuse address, with timestamps and affected IP's. That way, maybe something could be done to help disinfect the horde.
