Cloaking.

Google bans people, but mostly the innocent ones. If you're running blackhat, you've built a setup that gives you very good avoidance, and the bans are calculated into your sheets. The reviewer and the system sees something else than the customer clicking the ad. And even if they get banned, they will just burn a cc and domain and then get back to printing after a few hours.

While a legitimate business never suspects it can get banned, and when it does, the process is Kafkaesque.

Our case: a month of back and forth on the appeal, no success. The best we got was a suggestion to read the TOS and check whether we had any "brand affiliations" we don't have in real life. Previous replies were pasted slop. We don't have any affiliations, and we still have no clue what they were talking about. Meanwhile our conversion rate on other ad platforms was decimated by us constantly changing stuff to please the Google reviewer.
