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.
Affiliate percentages are reduced not only for you but for everyone.I also see in my account that there is a rate of 9.8%. So you have to accept it too. nothing to do here. So you have to deal with this if you want to earn from affiliate and choose BC.GAME site as your affiliate company. and if you think this percentage is low then you can try other sites too.
It's hard when you compiled a lot of referrals and you are sharing your rewards with your affiliate to motivate them to continue playing, if you are going to pick another casino you'll have to build your affiliate again and promote again but that's how things go on affiliate marketing, you have no control if they want to change the terms, even top casinos are changing their terms your only choice is to also change your terms on your reward program.
