Not just Facebook! I also regularly get obvious scam AI-generated ads on YouTube, e.g. for a weed killer with a video that shows the weeds wilting as soon as the substance is sprayed on, while the grass is completely unaffected. Or a car scratch remover that instantly returns any color of car to an as-good-as-new state. Or instantly adjustable glasses that work for any kind of sight impairment. Or (while it was still warmer) a miracle miniature air conditioner that could cool any room down in minutes without needing an external unit. Etc. etc. etc. All developed at or endorsed by serious-sounding universities or institutes (that have probably never heard of these products, same as Mark Cuban).
