Update: Just spoke with an admin, nothing he can do about it. I guess it's time I say goodbye to this site. Taking my 43 referrals and millions wagered every week along with me.
It is up to you and I think it will be a huge loss to the casino if 43 people stop playing on their site at the same time though I think it will not cause them to go bankrupt.
With every dollar being wagered on my referral now, I'm losing money.
Stop your service immediately because you are losing money here while casino doesn’t have any responsibilities on your losses since you are the one who offer it on your referrals.
It isn't pocket money loss but a paper loss since @OP is still calculating on the previous affiliate percentage commission which is revised recently by the site.
I get that sites need to make changes here and there, but they should never mess with affiliates IMO. They want users to join their affiliate programs and bring them players, but then once they build a base they take away the revenue promised.
There might be a reason for the cut-off, though we can only speculate but I believe it has something to do with cost-cutting. It is a normal occurrence in all business establishments that once their target is reached they either remove the marketing that aids them to that success or trim down the reward just to keep rewarding their contributors.
I'd say affiliates are a decent reason sites get traffic, why potentially take customers away from your site? Look for other ways to cut costs.
