We have actually gone completely ad-free as of today, apart from the ads that users run via our self-serve advertising platform. We did this even though it reduces our revenue just so that users have a better experience. As for the multiply rolls, 40 rolls is nowhere enough a large enough sample size to determine the fairness. We are provably fair and all rolls can be verified. Sometimes the server that stores the rolls history gets overloaded and so rolls can take a bit longer to show up in the rolls history (even then the delay should not be more than a minute or two). If any rolls are missing, please let me know the nonces that are missing and I shall check but I doubt that any are, it is just slow at times.

Previously when we had adsense ads we had different rewards based on the user's country as we earned different revenue from users of different countries. However since adsense blocked the website from their service, I have just normalised the rewards so the average rewards are still the same but they are now equal for all countries. Most other faucets who got their adsense accounts disabled have either shut down or reduced their rewards drastically but I have been able to keep the rewards more or less the same. We are still paying out 3.5 - 4 bitcoin in free play rewards and affiliate commissions every single day and I doubt that there are many other faucets that can claim to do the same.
