They don’t change… I had the same problem some 5 years ago. There was an ad for olive oil using the logo of a famous supermarket around here, and a fairly similar website to the supermarket one. I reported that ad 5 times, got the same “this ad does not violate Google’s policies” response each time. Until my mother clicked on it and was scammed out of her money.

I came to the conclusion that the only solution was to be done with google, I started using nextDNS in my entire network, changed all standard search for duckduckgo, and installed ad block all over.
