I think you are violated Google's Circumventing systems rule. I noticed your affiliate site is using woltcode.de as domain name but "wolt" is maybe registered trademark of wolt.com. Google cannot allow this kind of similar domain name in generall.

If only google would bother to explain why their AI banned someone, and gave reasonable methods to appeal

OP here.

Exactly. I would be happy to change the domain name if they bothered to tell me that this is in fact the problem.

Adwords support is Kafkaesque nightmare.

Didn't use to be this way.

It could also be due to a DNS redirect.

I hosted a page on AWS S3 bucket exposed to the web, and had my domain CNAME record point to the bucket public-facing DNS name.

Triggered the same Circumventing ban.
