Internet service providers in Belgium have been ordered to block traffic to several of the most popular online poker sites, including Bwin, Betfair, Betsson, and William Hill. The European nation has been weeding out more and more internet gaming sites as it continues to hand out its own operating licenses.

Currently, only PokerStars.be, Partouche.be, and Casino777.be are allowed to offer online poker to Belgian citizens. These three received licenses under the Belgian Gambling Act this past February. According to PokerNews, PokerStars managed to get by thanks to a partnership with Circus Groupe, an online casino developer.

For now, controversy abounds on the matter. PartyPoker and iPoker, two major players in the internet gaming industry, have been particularly vocal in their criticism of the Belgian government. Due to unresolved taxation questions within the law itself, they have dubbed the current legislation to be unenforceable.

Several other poker sites have already found their names on the blacklist. Among these are ChiliPoker, TitanPoker, EverestPoker, and 888Poker. As of yet, there has been no word on the possibility of further licensees.
