I'm surprised that so far have not already launched any campaign outside of this forum. Social media, Twitter or something for sure can help to promote Windice casino.
I think that's because the return on investment is very difficult. For gambling sites it is better to advertise where potential players are (like here). On twitter or facebook, it is very difficult to reach potential new customers because, on the one hand, there is a lot of advertising and, on the other hand, people give little chance to new sites due to ongoing scam incidents.
