While I understand the sentiment, most ads for a long time were fairly reputable? Like in the news papers, most ads were to make you aware of a brand (next car I buy I'll feel safe buying X because I've seen it in the papers), or to notify you about a local store having a sale etc. And disabling my ad blocker and going to a page I see ads for house listings nearby, offers to buy sports gear in a store in my city, and ads for a well known telecom company. All things I would trust.

What I don't understand is why high-value brands sell their screen estate to straight up scams or low quality ads.

I dunno, I’ve been doing some genealogy research and looking at a lot of newspapers from the 1800’s. It’s striking to me how much they are essentially Facebook. Sure, on the front page there’s the news of the day, but on the inside are jokes, riddles, local notes on who visited who and where. And the ads. Literal snake oil! As well as all sorts of other sketchy tonics for curing any sort of “ill constitution”.

I think those of us on this forum likely grew up in a golden age of ads being relatively harmless, but I’m not sure that’s the normal state.
