You know it when you see it... I worked in the newspaper industry on the web side for many years. Remnant ads are the worst. These are the ad networks that you use to fill up the last of your ad spots that you weren't able to sell directly. They can fill volumes of ad spots for pennies per 1000 ad impressions. These are pure trash. Ignoring the common problems with actual virus payloads that they might try to inject, these are the most obnoxious, awful ads. They often have big animations with flashing background and jarring colors. They are full of click-bait titles. They are the reason people install ad blockers. I might not be able to tell you what a quality ad looks like, but I can tell you the other end of the spectrum, and it is pure filth.
