Gday Webmaster,
Happy to help out with your questions 
Questions:
1) Do you carry over negative balance?
No, negatives are not carried over AND a negative result on one of our casinos does not affect positive earnings on another.
2) Is the winning player removed from the account?
No, the winning player remains tagged to the affiliate account. More often than not the player will return and play back some of the winnings and it only seems fair that the affiliate earn a commission from this playback.
3) The webmaster has to request a non negative carry over agreement?
No, as no negative carryover is our standard agreement.
4) Any restriction?
No restriction with regards to negative carryover whatsoever. No negative carryover is the rule and there are no instances where this rule is changed. You’ll never find yourself “in the red” with us.
Hope this helps!
Cheers,
Trish
