This is what The Guardian suffers from. It is slightly less-bad than it used to be, scrolling through an article on mobile would send you jumping around as new adverts spawned where you were reading - for the time being it appears to be within the first ~N seconds of load.

Steam suffers from it too - while clicking through your "Discovery Queue" it often displays a link to a video of someone streaming the game it recommended. Not that it matters now, Discovery Queue is hopelessly broken for me - only shows some very low-quality games i'm not interested in

Even funnier that there is a control bar for gfycat itself that gets covered by a cookie acceptance popup that shows up after a second or so. Try to pause this and you'll get blocked halfway through your own click.

That was a very scary day in Honolulu for all of us who live here. Ads will really be the death of us all, someday...

loool this is a serious problem
