The Belgian Gambling Commission has added three more websites to its blacklist of online gambling operators.
GG.bet, Syndicate.casino and Whitlioncasino.com all now feature on the blacklist, after the Commission discovered they had been targeting Belgian players without an igaming licence.
Operators that continue to run gambling sites without the relevant licence can be fined between €100 (£91.31/$118.43) €100,000.
Players who gamble on these website could also face criminal charges, with fines ranging from as low as €26 up to €25,000.
William Hill, Bet365, Betfair and 1xBet are among the other brands that are on the blacklist, while Asperino, WildBlaster and Madnix were also added earlier this year.
“It is prohibited for anyone to operate games of chance without a licence granted by the Gaming Commission,” the regulator said. “It is also prohibited for anyone to participate in or advertise an illegal game of chance.”
