So um, why exactly are botnets bad, wouldn't the additional hash power be beneficial for our cause?  Could the stats of the botnet please be posted so we can all get a better understanding of what the network was doing and why it had to be rid of?

Total Mhash toward pool
Total bandwidth of pool server(s) used (amount in percentage as well)
Blocks found
coins generated
shares
number of workers


Also, if bandwidth was the ultimate issue, what if the zombie network funneled work to a server of the hacker.  Would it have been better for the hacker to create his own pool, or could the hacker have have lumped all the data and submitted it to the pool from a single location, thus lessening the load of the BTC G server that would otherwise have to deal with multiple connections to thousands of individual miners?
