    Your screenshot suggests the advertisement is hidden in that "Answered X minutes ago " ( or whatever time/date ) text . I've never had it and it shows up for me as plain text. – Sergiy Kolodyazhnyy Mar 27 '16 at 18:39

    SE doesn't use doubleclick for ads. You're either using bad DNS or you have a nasty extension installed. – Seth Mar 27 '16 at 18:41

    SE uses adzerk: meta.stackexchange.com/q/238387/270345. One possibility is that your ISP could be inserting ads. – muru Mar 27 '16 at 18:42
  • Ah, sorry the screen capture is perhaps a bit misleading. The targeted element is in no way relevant here, it's just the console log entry that is meaningful. I'll fix it since I still have it open on my tabs. – Timo Mar 27 '16 at 18:42

    Stack Exchange does not use these companies/URLs. You're not getting them from the site. – Seth Mar 27 '16 at 18:53
  • @Seth, are you sure adzerk doesn't sometimes use third party advertisers like ad.doubleclick.com? I find it quite difficult to believe that Finnish ISPs would swap askubuntus SEs advertisements to something more of their liking. Likewise I'm finding it difficult to believe the problem would be in their/my DNS. What it comes to extensions I do not have any extensions installed except for Ember Inspector and Google docs, cast and docs offline all of which I'm quite sure are safe to use. – Timo Mar 27 '16 at 18:58

    Stack Exchange is very strict in what advertising they use. They're the only company I've found that even has a contingency plan for users in case they someday go rogue.. So, yes, I'm sure. I'll ping an SE dev to take a look in case this is happening and they don't know, but it is very very unlikely. They probably won't respond until the weekend ends. – Seth Mar 27 '16 at 19:00

  • I'll attach the full html page for the askubuntu question, but looking at the source it looks like adzerk loaded inside it's iframe another iframe from another advertisement provider. – Timo Mar 27 '16 at 19:04

    If you don't want to see the ads, whoever and why ever they are coming, you should just use an extension such as Ad Block Plus. – user364819 Mar 27 '16 at 19:09
  • The ads on SE are all static images. And for me, adzerk loads no iframes. There's just a regular div with an img for the image, plus a couple of divs for voting buttons. – muru Mar 27 '16 at 19:11

    This isn't a problem on Stack Exchange's end. It's somewhere either on your machine or between your machine and the SE servers - not only does Stack Exchange never serve animated ads, nobody else seems to be able to reproduce this. – ArtOfCode Mar 27 '16 at 19:13
  • @TimoLehto: you're not seeing the ad animate, correct? I don't see it animate either, but I don't think that's your concern. Can you be a little more specific? – stevvve Mar 27 '16 at 19:14

    Also: you all are correct, we are exceptionally strict about what kind of advertisements we allow on SE, but DoubleClick is not necessarily a questionable source. It simply hosts creatives for which they generate creative tags which we then upload to Adzerk, our server, who kindly delivers the creatives to SE. If there is a something malicious going on here (which is unclear to me as yet), it won't be just bc the creative is coming from DoubleClick. More important: can anyone repro the error? – stevvve Mar 27 '16 at 19:23
  • @muru, obviously the ads are tailored to each individual and whatever information they have about you. With incognito I get a different ad, this time without errors, but the structure is about the same and the end source is ad.doubleclick.net, but ofcourse they still know my ip at least so they know something about me, so you might get different add. – Timo Mar 27 '16 at 19:32

Thanks for letting us know! I've reached out to the advertiser to let them know about the error and I'll update here when it's resolved or I have more info. (FYI, I work on the SO Ad Ops team with stevvve).


Update: The advertiser has removed the troublesome Bizible tag completely, so we shouldn't be seeing this error anymore.
