A client's (medium-sized news portal) Google Ads account was suspended a couple of weeks ago without prior warning. The only reason Google gave were the two words above. Consulting Google's help page Advertising Policies Help: Abusing the ad network. proved not very helpful as my client has never been involved in any black-hat SEM operations. Neither did Google respond to inquiries by e-mail or phone.
What makes Google accuse an Ads customer of "circumventing systems"? And: How can I get the account reactivated? Thank you.
EDIT: After talking to my client once again, I found out that they also use two accounts (not one) both for AdSense, and for Google Ads to promote their own websites (and nothing else). The accounts were suspended a couple of weeks after they had implanted a new cookie consent dialog on all their websites. May this be the cause?
