History
In May 2006, YPN caused some controversy by shutting down accounts used for MySpace layout sites. The reason given was the quality of traffic was very poor.
Also in May 2006, the Yahoo! Publisher Network's blog posted an updated version of their requirements from publishers. YPN explicitly stated visitors must recognize advertisements as advertisements, and images/media could not be placed to induce accidental clicks.
