DraftKings and FanDuel may have bitten off more than they can chew when they sued New York to keep their daily fantasy sports games alive in the state. FanDuel's corporate policies from before it self-regulated have been entered into evidence, and some of them only seem to confirm worries about staff abusing their power while playing on rival sites. For a start, the site told workers to "never be among the top five" players on any daily fantasy site, or the top 10 on the tracking site RotoGrinders. They also couldn't have disproportionate numbers of entries in tournaments, and they were supposed to avoid using information on player lineups whenever possible. In other words, don't be too successful -- we don't want you raising suspicions that the games might be rigged.
