I did a site targeting campaign this morning, and went to one of the websites to see if my ad was being displayed. My Ads were being shown, and when I clicked on an ad to test it, the entire landing page loaded in the 250X250 box – so I could barely read my landing page. I deleted that specific site URL from my campaign. I checked the site later, (probably 30 minutes later but not sure) and my ads were still showing.

It seems to have stopped now though...but that's pretty sketchy.
It cost me $15 more than I intended to spend (big deal)...
but when your dealing with hundreds of thousands of impressions that can add up to thousands of extra dollars!
I don't expect it to pause instantly, but this seemed a bit too long.
