Could you share a little more about the sockpuppet detection? That sounds very fascinating. Do you specifically mean IRA sockpuppets, or Internet sockpuppeting in general?

Or using text from known sockpuppet accounts to predict if other accounts may be sockpuppets? Some combination? How much stylometry was involved?
