It's less then pennies per view. All of those trackers also pay less than pennies per view. Basically, if you have a legit business with any ability whatsoever to make decent revenue, there's no reason to have chumboxes or paying trackers on your site.

Let's not beat around the bush: some publishers do that kind of thing because they are scumbags.

Probably some exec is standing in the middle of the war room screaming at the top of his lungs that revenue is down and so people get desperate not to lose their jobs and start sticking this crap at the bottom of the page. Some money is better than no money they think.

I don't really agree. I don't think that's fair.

It's presenting your audience with misinformation, false hope, and scams. It's incredibly scummy. Those type of ads prey on people's desperation and gullibility, and there are actually people who will fall for them and waste time and money in the process.
