It's probably not their problem anymore if you don't make money out of it since they are not involved with your decision to pay bonuses to your invites. You should also adjust with the new rates.
It still says 35% on the affiliate page, but it has been decreased to 9.8% The affiliate program is not lucrative enough for me anymore, I'm probably gonna migrate to a different site along with my referrals if BCGame still choose to ignore me.
Also BCGame have been costcutting so much lately, the removal of rakeback, slashing affiliate %s and so on. I would advice people to stay away from the site as it seems like this is the start to something worse happening.
The fact that the term and condition of the term of service states that the casino have the sole right to make any change makes it difficult to place blame on the casino since their already made the law that will protect them against the player in any of their programmes and services.
But the reward disparity between your old affiliate payment and the current one is too much and I suggest you reach the team to explain to them and ask why so much significant decrease in your percentage payment as an affiliate payment.
And on the other hand, you will have to communicate the change of payment rate to your downlines that tho pay 10% to unless you want to continue to service them out of your own pocket since the reward is no longer coming as before.
