Hi Ellen,
Yep. I can steal your fun players by having them sign up under a new email address.
But isn’t that the case with many places?
Cryptologic allows a person to create a new e-cash account every time they sign up for a casino. I have signed up at Intercasino (seriously, because I lose the previous info and don’t want to wait for support), at least 6 times , probably more over the years.
I’m quite certain that the old affiliate does not get credit for the new sign up.
