The problem with gambling is, there are so many other readily available alternatives. Yes, DFS could maybe cut him off if he loses &quot;too much&quot;, though how we define that is too difficult. If a guy who makes $50k a year loses $50k, that&#x27;s probably too much. If Mark Zuckerberg does it&#x27;s not. DFS sites surely can&#x27;t be expected to know your financial situation.<p>But anyway, suppose they could. There&#x27;s always the world&#x27;s biggest casino: the stock market. Or there are actual casinos. Or there are lottery tickets.<p>In most gaming jurisdictions, casinos are required to pay for billboards and the like advertising where a problem gambler can get help. (The lotteries, which are state run, never do this, and Wall Street sure as shit doesn&#x27;t.) I&#x27;d have no problem with those sites putting link to Gamblers Anonymous on every page.<p>But beyond that, I don&#x27;t think they have responsibility.
