The irony here being, after I read this article, I'm now seeing ads for mattresses all over the web due to the embedded ads in the article. Marketing and advertising feels more like a virus than anything these days.
Not an AdNauseum user myself, but how can we tell this isn't ad industry FUD? They would certainly have a vested interest in discouraging the practice.
If nothing else at least AdNauseum can contribute somewhat to bandwidth and administrative costs.
Bandwidth costs would be a few extra bytes and you would likely only hurt yourself if using a metered connection. There are 0 extra admin costs.
If you don’t like the ads then avoid the site, but if you must still access the content the use an ad blocker because loading ads just to falsely click on them only generates a stronger signal than usual.
