I have reported over a dozen ads to AdSense (Europe) because of them being outright scams (e.g. on weather apps, an AdSense banner claiming "There is a new upgrade to this program, click here to download it") . Google has invariably closed my reports claiming that they do not find any violation of the adsense policies.
Same thing with Instagram, they accept all scam ads.
Google and Meta are trillion dollar criminal enterprises. The lion's share of their income comes from fraud and scams, with real victims having their lives destroyed. That is the sad truth, no matter how good and important some of their services are. They will never stop their principal source of income.
They’re far too embedded politically to ever face consequence too. I hope someday we can get a serious anti-corruption candidate.
Do you report those only to Google, or also to your local watchdog/police/commerce regulator?
