This shit happened to me when I was loading pages through a proxy installed on my own network.Same network but different ip, and on that ip I installed a proxy ! Since then I never saw that Is that your case ?
Do not filter out these advertisements! I was getting the same message temporarily, but as my earnings have increased greatly today, I'm under the impression that DELL appears to be paying more than any advertiser in the past. The issue, from my knowledge, was with them not having sent their image advertisements despite having initiated the campaign.
Well i know what must have happened Dell guys have created the ads but kept them on hold till they get the "Description or images" for the Ad. Now this could just one of the ad out of other 20-50 ads they want to go live, those ads could be ready to go live. Someone from their team screwed up and put all ads live without noticing that this is yet to be polished. Makes sense?
