"I never saw most of the offending ads because of my adblocker, so I didn’t notice the changes or experience any irritation personally. "

If you run a website that serves ads, whitelist it in your adblocker so you can see what your own damned site looks like to people who are still rawdogging the world wide web.
This is why I greatly prefer podcasts where the hosts read the ads. If you're going to take ad money, you better be willing to sell it with your own voice. All else is a descent into scam ad hell.
Most people who ran AdSense were extremely careful not to look at the ads on their own site, because Google might flag them for intentionally inflating clicks or views.
