I'll never bemoan a success in the victory against cybercrime, but it would be nice if one of these announcements came against a botnet that was still relevant and sending out large amounts of spam like Rustock. When the trumpet was sounded by Microsoft about the death of the Storm botnet, it was about 18 months since it had been highly relevant.

As others have said, shutting down individual botnets doesn't have long-term effects. That lesson was learned when McColo was taken offline.
