It is just changing and the trend today is a lot different when it was first conceptualized. Newer trends are more restricted and affiliates are now refrained from practicing link-spamming while banner displays are reduced. To me, this sounds like a good thing!
Google’s algorithm is also strict about contents as well as SEO practices and websites who fail to comply with the standards are shifted to the last part of the search results page. Banner ads are restricted simply because they are not compatible with mobile phones these days. The sizes of the images used alone are not as effective as they used to. Today banners are replaced with text links that you can find between blogs you read.
To me, it sounds like affiliate spamming is dead and that affiliate marketing is very much alive.
