actually they may created a illegal gambling site as extension if the taxes will be as high that they cannot expected.
I don't think they would do that.
They would continue to offer their services to these gamblers and at the same time, follow the policies needed or required by the government. I think instead of the owners avoiding that huge taxes, I guess it would be the people that would do that. They've been taking care of these gamblers for so long and I don't think they would risk that for avoiding those taxes.
