"Vaca Daffan filed a lawsuit [...] in the Superior Court of the District of Columbia on behalf of the National Association of Consumer Advocates against Blockratize, Inc. d/b/a Polymarket and related entities, as well as Shayne Coplan and Matthew Modabber. The complaint alleges that the defendants orchestrated a sweeping and flagrantly deceptive marketing campaign that lures Americans into risking real money while obscuring how likely people are to lose. The complaint also accuses the defendants of unfairly targeting college-aged individuals with manipulative ads for their platforms."
