Absolutely NOT. They can purchase adspace if they wish, but listings are and will ALWAYS be free. Otherwise a casino may think they can bribe us to be at the top. We started this site so that these casinos would be held accountable - not so they could pay their way through a lie.
Also, yes, we will link your post in our email for each of these sites.
Right now BetCoin.TM is fully integrating with our service so that you can paste your game ID in their checker and we will pull the details and run the calculations on our end. I want to see more casinos do that, but it's a bit of a hassle. These other established casinos will hopefully follow suit because it's a super nice feature and I think users will really appreciate it.
