Romania’s gambling regulator National Office for Gaming (ONJN) posted its first blacklist of online gambling websites, enforcing taxes payment on operators’ unlicensed activities in the country.

ONJN has banned 48 domains and have been given a 90-day grace period to pay 20% on gross gaming revenue earned in the country over the past five years until August 1st 2015.

Among the casinos listed on the Romanian government website as operating illegally are several Casino Rewards properties such as blackjackballroom, carbon poker, clubworld, intertops, lasvegasusa, and slotland.

Other major operators such as bwin, PokerStars or Bet365 are reportedly negotiating the retrospective tax bill they are being asked to pay by the authorities for operating in the market without a license. William Hill does not appear on either list as its last day of operations in the country was June 1.
