Turn on many pop or hip-hop stations in the US in the morning and you'll hear the actual morning show host endorse all sorts of products that sound like a scam: discount cosmetic surgery, car rims for rent, accident attorneys and more.

In many cases I've heard them advocate as if they've used the product or service personally and got a good deal and there's never a "paid ad" or "promoted content" disclaimer (or maybe it runs at 3 AM?).
