Newcomers to sports betting, and particularly daily fantasy sports (DFS), could be forgiven for not knowing much about the history of FanDuel and DraftKings. The two operators have recently become respected partners of giant corporations like Disney and have led the sports betting revolution in the U.S.

One lawsuit is looking to remind everyone that the two sites have a history of controversy, and help their customers win back some of the money lost on their platforms. Troxel Law have put up the website dailyfantasysportsclaim.com, specifically looking for customers who have lost funds on the two sites since January 1, 2015.

The site spells out exactly why they believe there’s a case to be made against FanDuel and DraftKings, and they believe it’s a case of false advertising:

“According to the lawsuits, FanDuel told its investors that only the top 0.1% of users actually win money, and only a tiny minority of DraftKings players won money over the long term.
