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.
Besides the trackers and malware, ads can be categorised as a flaw in technology. A kind of software parasite that uses a computer’s resources without providing any additional functionality to the user.
Ads are malware (software maliciously made to do something the user doesn’t want), yes. :3
