If a sponsor wants a version of the game not containing ads, is there a simple way to block the ad for the sponsors site?
Yes, we allow domain filtering. When you enter in a domain to be filtered, whenever the game is played on that site, we will not show any network or custom ads. Each domain you enter will be filtered. This way, if the game gets copied to another site, then ads are turned on and you make more money. No need for domain locking!
