Huh, you are right. Those scummy links at Washington Post are all Outbrain. I was mistaken then (because they use BOTH Google and Outbrain)
Scummy AdSense ads are harder to pin down, of course, because of the live bidding and personalization.
EDIT: There's another one at the bottom of the page too. And they're randomized, some make it clear you aren't downloading Paint.net (such as the "Free Mac PDF Reader") but others aren't at all.
