These companies know they break the law,” a Justice Ministry spokeswoman said on Saturday, adding that Swedish online gambling company Unibet and Dutch firm Oranje Casino were targets of those requests. According to the spokeswoman, a list of about 50 online gambling companies has been created and distributed through the local bank system with request banks to stop financial services to these companies.

Dutch justice minister Ernst Hirsch Ballin has promised to crack down on the illegal online gambling websites in the country, according to news reports from the Netherlands. According to the Dutch justice ministry, it’s currently targeting both foreign-based gambling companies, as well as domestic, but refused to give divulge more details or any specifics. The justice minister also warned the local banks that they may face legal action, as well, since they would be breaking the law if having gambling websites as their customers.
If I was a BIG player, I would probably open a bank account in Belgium or Luxemburg for gambling.
