I've a site that's been featured a number of times in a number of places. One of them was being nominated for a webby award. But it's also been featured on TV, radio, magazines, newspaper articles etc. I've always collaborated with those I considered to be genuine.
But if Google's Adsense were to ask this, I'd decline. It's calling undue attention to the ads.
And having ads is counterproductive to a lot of things in itself, adding attention to the ads can only make it worse.
