From a New York Times story by Eric Lipton and Kevin Draper headlined “First Came the Sports Betting Boom. Now Comes the Backlash.”:

Legislators and regulators who began the headlong expansion of legalized gambling in the United States are now moving in spots nationwide to tighten oversight of the gambling industry, particularly as it relates to advertising that may reach underage bettors.

The crackdown extends to bettors themselves, as at least three states have responded to a jump in abusive behavior by moving to bar gamblers if they threaten or harass athletes after lost bets.
