How common? Pretty common. I actually considered trying to make a business model of building low content/automated sites and monetizing through these guys. The amount they pay in general beats adsense by a factor of 10 (or 100) on a low traffic site. Their interest is the link, most sites with no maintenance or work are getting low/no traffic but may still have ranking weight. So it's an easy way to make them profitable. Consider WP Blog + cheap hosting + domain. We're talking costs of ~$10 per site. You take average $150/year on an ad. You only need 1/15 sites to get approached to make this profitable. I'd say I get approached 5-10 times per year on 30-40 sites. The math is mildly attractive if I lived in a low cost country.
