There are three main kinds of ads I see: (1) products I just bought, (2) products I would never ever buy, and (3) creepily manipulative clickbait. None of these should be worth the money to the advertiser.

I test drove a car and after I got almost a dozen follow up calls while I was busy with other stuff, I blocked the dealership number. They kept calling me from other numbers, which I also blocked (with the new Android spam filter on my phone). But the amusing thing was that I started seeing ads for the dealership online promoting their "low pressure" sales team!

I made fun of a company called Salsify for naming their business after oyster plant, a root vegetable I can't stand, and now I see ads for them all the time.
