Plus you won’t be able to step in to the USA ever again
Why do you say that? How can they check which sites I have? And do they care?
A white label casino is just like any other affiliate. Instead of linking to a site, you link to the download software, like other brands allow 
Payments by Neteller or visa credits. Will they check all of them, before allowing anyone in the country? Are we terrorists, lol?
Do you know why I like private / white label sites? Because there is no way they can bypass my affiliate code, clean cookies, or any other things.
Some people hate affiliate links, and we have to deal with that.
And I’m not talking just about gambling sites. Until now, for more than 7 years, I only heavily promoted sites that allow me some customizing, and hosting (partially) something.
