Maybe the answer to this is obviously yes they do. I am guessing, but since redirecting renewed sites sounds like a gray area for spam, seems like some will allow it and others won’t.
I have never thought about using redirects to my affiliate links, but it sounds like a great idea. As long as you make more than you are paying for the domain and hosting, it can be profitable.
Opportunity usually comes disguised as hard work. So I’d say something this easy has already been saturated by other gambling webmasters, who have worked on it. Right?
