I live in Eastern Europe. 1/3 ads I have seen during the past month while reading google news, have been scam ads. My eye is pretty trained towards them. I even reported some that I thought are REALLY crossing the line, like the one that used AI generated image of Prime Minister of my country, leading to a phishing site. Each time I’ve reported it to google with proof, the answer from google has always been “this does not go against our terms of service”
