Ironically it's only really people who heavily ad-block/privacy-protect that get these scam/malware ads.

When Google has no profile on you, your view is virtually worthless, so it's only bottom feeders that bid on those views.

Average users get Coke and Tide ads. Its usually the most technically adept that get the worst ads, and usually they just turn their ad block back on.

I recall a articale I read "somewhere" that reported the Facebook makes big profit (Billions) from scams. So they have no ( or no strong motive) motive to shut such scams down

An example is courtcase against Meta for using a Australians mining billionares likeness to promote a crypo investment scam.

Imagine how world would be different if the actual scammers and malware creators would be prosecuted and not insteead demanded that internet giants play a privatized police force.
