I've not seen the ad, but I agree that there are ads that appear on 3FC that are questionable. Most of the ads here are google ads, which display ads based on keywords so 'diet' can pull some humdingers. Unfortunately, I no longer own this website so I don't have control over it. I worked diligently to block questionable ads using the google ad filter when it was mine. I'm very sorry that you and the other members and visitors are exposed to it
