Well, they make a limit to try and make it possible for everyone to compete, as a sales tool. (ethically questionable for this sort of contest when they cannot police a syndicate like this circumventing that limit easily)
In a week like this there was far less high % chance lineups than usual, so if there were unlimited entries maybe a lot of people would have shared first prize.
So a syndicate working as one effective entry has an extra large unfair advantage over people following the published rules in this NFL week.
One question that still comes to mind though... if fantasy is so corrupt and "everyone cheats" using syndicate entries like this, then why did they win the first prize alone?
