Posting this in this thread because I think it fits the theme.
Check out what Polygon did:

They posted a Microsoft ad as a news story, and then defended it by deleting comments pointing this out and complaining that "everyone is on a witch hunt" on Twitter. Open mouth, insert foot.
I wasn't honestly expecting much from them, seeing as they appeared to be a Voltron formed out of some of the worst parts of Joystiq, Kotaku, and IGN, but when a site claims to be "different" it's much more damning when they pull the same old advertisement-as-news crap as a lot of the other sites. And then tries to cover it up and play the victim. The first is just usual crap, the second takes a special kind of ignorance. The Internet never forgets.
