Well "ad fraud" is an official name for this kind of behavior. Consider in an advertiser's perspective, I pay to get someone see my ad, and I even pay more if people click on it. Now I've paid the click price but my ad is not seen by any real person. That is fraud. It might not be the user who use the adblocker committing the fraud, but that user is getting involved. And the website ( unfortunately might not have any control on this entire thing) is pulled into this chaos by the user and adblocker, and will get harmed.
