How about articles written by human charlatans? Claiming they are 'doctors' or 'scientists'. Or posters claiming something that didn't happen? Like a... pro bullshtter claiming he was denied apartment renting because of his skin color. He could make a lot of money if that was true. But poster is still taking ads place, payed by poor 'suffering' minority. Another example 'influencers' who pretending, or really being, experts advise you on forums about products. The tell mostly the truth, but avoid some negative details and competing products and solutions. Without disclosing their connections to businesses.

Shorter version: intentional bullshtting never ends, it's in human, and AI, nature. Like it or not. Having several sources used to help, but now with flood of generated content it may be not the case anymore. If used right this has real affect on business. That's how small sellers live and die on Amazon.
