Hey Scandle many things can cause you to gain big leaps in new players, I’ve seen affiliate links take top spot for a searched casino name in google it never lasts long but when you get top spot massive surges happen, maybe that was the case.
However if you are on a CPA deal the day will come when the casino looks at the bigger picture – deposits vs profits vs your CPA Deal and if its out of sync you will get placed on a profit share deal, if its the other way you will be kept on CPA.
Any respectable casino will pay what your owed unless of course its obvious some skull duggery has been happening
Let us know how you get on.
