Before revision:  The data collected during the US election campaign, contain original tweets from 822 troll accounts which have been identified as such , based on archive data released by Twitter related to state-sponsored trolls' campaigns. Then, we constructed a very large interaction graph of 9.3 million nodes and 169.9 million edges , where using graph analysis techniques  along with a game-theoretic centrality measure  , we quantify the influence of all Twitter accounts on the overall information exchange as is defined by the retweet cascades.
