While he was working as an advisor for Kirov district governer, he supposedly forced contracts with disadvantageus prices on state owned company with a total of 16 mln rur (roughly 500k usd).
I didn't read court documents, but I wouldn't be surprised if he actually did.
Fact that he blogged about corruption for a few years doesn't make him innocent, but government probably would never looked into it if he'd keep quiet.
