The worst are the companies/people imitating US government services like post office mail holds and passports. Search google for "us passport" and check out the sponsored links "owners" of the ad.. they look like phishing scams!
We need laws outlawing the misrepresentation of legitimate government services. Until then ad-block is the only solution if Google won't act appropriately. I can't imagine how many people have fallen into typing the SSN into such websites.
We have some, which should probably be broadened:

Every time you see these scam 'ads' or sponsored listings, report them. Every time you get something unsafe from Amazon (for example I submitted the semi-recent Youtuber investigating fuses that are unsafe) report it to the FTC. The agencies that stop this initiate action from reports. Which means you have to report these things.

They blocked my ads account before I had the chance to run my first ads with no provided reason and no actual way to dispute with a human being. It's houseplants, not drugs. And what's worse is that you can clearly see all kinds of scams and gambling ads running amok in the wild. Their detection and support systems are both abysmal.
