First, I have no negative balance at RR (to blueman).

Second, while I thank you for your response (RR) and while I unfortunately cannot show you which affiliates absorbe that cost, I know they exist and perhaps somebody will step forward and name a few.

Finally, FT is a site that sets a rakeback limit to 27% to the players while the affiliate, the more customers he brings, the higher the % he gets back. This, again, it is something I have heard from, in my opinion, reliable source but I have no means to confirm.
If it is not true, then I understand your position (I don't like it, but I understand it) but if it is true that the affiliate keeps earning more and more whithout the possibility of giving more back to the players (an excellent FT rule in your eyes, not that good in mine) then it would only be fair that you absorbed those costs.

Kindly,
William
