OK, this has got to be the poster child for star-crossed media buys...
I was just researching a US agricultural vortal and a banner with a very hip-hop design for "Dr Jay's Urban Clothing" came up. I wouldn't be surprised if the webmaster hears from his regular users about that one. Hehehe! Still makes me chuckle to think about it.
Gambling.. farming.. Yup, pretty close to the same thing.
I did happen to see casino banners on an Ag site and wondered about it. As a travel & relocation site publisher, the only complaint about banners I've received to date was related to online gambling. Of course, I had just about every "offensive" ad server category blocked already.
