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.
My assumption was that they changed their program which would apply to all members. If what you're saying is that they cut rewards for certain players only then that's a different thing. Cost cutting is not the problem since every business does that but they should at least be more transparent if that was the case.
