Casino.com have changed a couple of terms in regards to affiliate commissions.  They are simple changes, outlined below, and not predatory, retroactive, changes:

TERM REMOVED

5.1 The affiliate earnings payable to you by Casino.com shall be calculated in the manner specified at http://faq.casino.com.

Summary: Affiliate earnings calculations are inside the terms and conditions, so the clause was removed in order to remove the URL which no longer pertains.

ORIGINAL TERM

5.2 The affiliate launch offer of $40 USD bounty per first depositor is subject to referred players with a minimum turnover of $40 USD and a minimum deposit of $40 USD. The 40% commission is in addition to the bounty awarded. This offer will only be available during the launch period. After this period has ended it will revert to a standard tiered affiliate programme to be specified at the time of change.

NEW TERM

5.2 You must specify whether you want your affiliate account to be Cost Per Acquisition or Lifetime Net Revenue Share. You may only select one per affiliate account, meaning you will be subject to the same conditions for all referred players linked to this account.

Summary: The reason for this change was the fact that the original promotional bounty is no longer offered.  The terms and conditions now more closely follow their true architecture.
