Yes, I agree with Webber and Big Daddy. It really is how to monetize the traffic with your “free giveaway”. You have to be careful with the editor process as they will quickly throw you out.
I had some sites that were up and then banned by google even without links, etc. They referred to “deposit bonus” and that was enough.
I agree about not flagging the guys who are there – kudos for them for getting around the system.
I wish more people could get around the US gambling “ban”.
