i personally feel that signature campaign here will only create the brand awareness. But won't given any conversion. Because most of the people in this forum are active here only to carry the signatures and make money. They will not sign up in the gambling site. Even if they sign up, they will use only the faucets and free giveaways. Showing the ads to the people who are here only to market is not a good idea i think.  We need to advertise in the area where there are consumers. I may be wrong. I wrote this based on my experience.
