Affiliate marketers often use shady techniques to get the click. It's a tale as old as time.
Wasn't there some browser extension years ago that was inserting it's Amazon affiliate link into webpages?[1]
A large amount of the spam we receive in our email is ulimately just some affiliate trying to earn a commission. Affiliates don't have ethical rules they need to follow.
It's very, very hard to find the "old days" true affiliate that drives any significant traffic. It's way more profitable for affiliate marketers to force users to open a new browser window which drops a cookie without the user having any true intention to buy, with the aim to scoop up the commission any future purchases.
I mean if you can trick a million people into clicking a link, you can make money as an affiliate. Or you used to be able to do that.
