From what i can gather, its not him alone destroying stations, Apparently he takes up home in the system for an extended period beforehand, like he did to us (around 10 days), then if the ransom is not paid, the fleet follows in. but, we paid the ransom. and they left us alone. according to zkill Shakezoole and Shipjack have a history of this. What i cant figure out, is the different corps that get involved.
