They call it “dark traffic” - ads that are not seen by tech-savvy users who have excellent ad blockers.
Not surprised that its growing. The web is unusable without an ad blocker and its only getting worse, and will continue to get worse every month.
I personally am not bothered at ALL by the banner video ads overlayed on top of another banner ad that opens a new tab when you try to close the banner video then another one opens covering the original banner then the page scrolls all the way back to the top and shows you an email list sign up, why would I be?
