Today I saw a big ad with width 300, height 600, a sidebar ad on Cross Validated. This is quite annoying because I frequently visit Cross Validated at work.

    It should only be 250 pixels high. – Sonic the Masked Werehog Sep 12 '19 at 2:37

    @Sonic where did you see it? From what I know, SE does not limit their ad providers anymore. – Shadow Wizard Wearing Mask Sep 12 '19 at 9:39

    @Sonic if you mean the CSS height imposed in the HTML, it's very easy to bypass by simple JS used by the ad provider.. – Shadow Wizard Wearing Mask Sep 12 '19 at 10:21

    @SonictheAnonymousHedgehog There are different ad sizes allowed now, I've seen them myself. – Mad Scientist Sep 12 '19 at 11:04
  • @NicolasChabanovsky isn't this status-bydesign? – Luuklag Jan 8 at 13:37

    @Luuklag Well, it seems to be tricky: as I understand from the accepted answer bellow 300x600 should be allowed only for some set of partners and it was a test run. On the other hand, technically that was not a bug. So... Let me correct the tag line as you suggested if it makes more sense. – Nicolas Chabanovsky Jan 8 at 13:43

Thank you for reporting this. It's very helpful. We were testing and will be restricting the 300x600 for most campaigns. However, you will potentially see those type banners for some of our premium endemic partners.

    Quick question: will these "premium endemic partners" also be allowed to run animated ads and use Flash? – Shadow Wizard Wearing Mask Sep 13 '19 at 6:19
  • (Why isn't there an indication for staff, as for moderators?) – P.Mort. - forgot Clay Shirky_q Sep 13 '19 at 9:37

    @PeterMortensen There is, but it's on the profile, as explained here – Secespitus Sep 13 '19 at 10:50

    @Secespitus It's actually also in the user card but those only expand once a user has 1k reputation, so it doesn't apply here. :( – Catija Sep 13 '19 at 14:51

    @Catija There should probably be a minor feature-request to make the usercard expendable for staff regardless of reputation. – Mast Jan 8 at 14:11

    @Mast I don’t think we know that on page load, so it’d be expensive to add. I think there’s discussion internally about just giving everyone expanding usercards. meta.stackexchange.com/a/336683/284336 – Catija Jan 8 at 14:28
  • @Catija That would probably be the most sensible way to fix it at this point, yes. – Mast Jan 8 at 18:35
