I’ve done this before and see nothing wrong with it. I did it in an attempt to keep the traffic; those that didn’t choose to sign up.
the site was an exact duplicate. I used their stuff to make it. provided a download link and IF the surfer then decided to NOT download the casino, … that way I was still able to keep the traffic that if I had sent it to the actual casino website; I’d not have been able to keep.
I think its smart.
