Here is what you pm'ed me:
Hi Nigel207,
In our T&Cs,
, term 8.2 defines this issue clearly - % itself is not the only criterion.
In the event that To Play Central (Ltd) believes You are abusing or attempting to abuse a bonus or other promotion, or You are likely to benefit through abuse or lack of good faith from a gambling policy adopted by To Play Central (Ltd), To Play Central (Ltd) may at its sole discretion, deny, withhold or withdraw from You any bonus or promotion, or rescind any policy either temporarily or permanently, or terminate Your access to the Services and/or block Your account. In such circumstances, To Play Central (Ltd) shall be under no obligation to refund to You any funds that may be in Your accounts other than Your original deposit amounts, this includes and is not limited to:
8.2.1 Moving from high wager values to low wager values, after high pay out values to achieve play through requirements. Such game play will be investigated for bonus abuse and game play will be subject to review and if deemed to be abuse all winnings will be voided.
Thanks & Regards,
Sacha
In my case, I bet $20 on slots, hit a nice win, and changed my bet to $3, and that is precisely what you decided was "bonus abuse" that "violated the spirit of the bonus" and confiscated. You say specifically in your pm to me that moving from a higher wager value to a lower wager value is "bonus abuse", and further you say that changing the bet is not the only criterion you can use, and its entirely at your discretion. In other words, you have terms that allow you to confiscate based on whatever it is you feel like is "bonus abuse" and no hard definitions of what is or is not allowed.
