They're not trying. I've seen an advertiser remain active for months with literally tens of thousands of ads where clicking them directly downloads a malicious exe file that most antivirus scanners flag.

Tech support scams still?! I don't even understand how this is possible. If Google wanted to they could come up with the tech to bypass the spam/scammers own ghosting system. They must have some kind of invisible Google bot that checks for downloads/scams, right?

Phone providers should also be detecting this with AI. There is no way this should be occurring anymore.

They make money on those ads, you’re asking a mega corporation to make less money. Good luck.
