Besides the miserable experience unchecked advertisements cause, it is simply not safe to allow those advertisements to load these days.

A few years ago (before SSDs were common) there was unusual PC hard disk activity when loading a popular link aggregation site. A bit of investigation turned up a Trojan on my system. After removing it and reloading that site, my PC was immediately reinfected. The site owner denied any responsibility and said it was the advertising company’s fault.

The way the Internet operates now means no one is responsible for the content their site provides or the damage they cause. Imagine if restaurant owners were able to deny responsibility for the atmosphere in their establishments or food poisoning episodes they caused? IMO it’s the same thing.

Advertisers and websites have created the “dark traffic” mentioned here by repeatedly poisoning the public and they deserve the massive loss of revenue their behavior has caused.
