Since it is not something users are requesting, for now, we will just take note of how many credits you have (of course, we will send you an e-mail with the amount) and reduce it to zero so ads show up again. If you want them removed again, just tell us and we will restore the ads.
I understand you will want to make some tries to see which ads come until you decide to keep them. That's ok.
