That's very unfair. You must had a mutual understanding with their affiliate manager and hopefully they did not drop it without giving you enough time.

Problem with affiliate marketing is, you do everything to make them big but when they are big they kick you out without showing a minimum respect. If you are really too good to bring so many affiliates and helping them to make that much money, then why don't you consider having your own gambling site. Have your own business and bring the traffic by yourself.
