When the pro football player died after being thrown from the back of a truck, SI.com was posting the news. I went to their home page and there was a picture of the dude front and center. Bad thing was that the ad rotator detected auto accidents and displayed Liberty Mutual Auto Insurance ads top, right and bottom of the page. To make matters worse, an overlay ad appeared right over the player's picture. The ad was translucent to give you the impression that it was auto glass. Then it shattered.
Really poor timing of an ad. I wrote the webmaster a note and the ad was pulled right away. I even got a response back thanking me for bringing it to their attention.
