There is this active thread at DigitalPoint Forums named Yahoo Publisher Network Terminates More Publisher Accounts that discuss the recent termination of those who run Yahoo! Publisher Network on MySpace accounts. JenSense has a ton of details on this but that really sums it up. Yesterday, Willam Johnson, the face behind the Yahoo! Publisher Network team posted at the YPN Blog an entry named Maintaining a Quality Network addressing the DP thread.
As noted on certain message boards, some publisher accounts have been recently closed. These account closures were based solely on traffic quality issues
He explains that this program is still invite and beta only and Yahoo! is still working on balancing the publishers and advertisers. I think Yahoo!'s stand on removing some of the "lower quality traffic sites" is a good move and will help Yahoo!'s program stand apart from Google's AdSense program. With MSN, we have yet to see how they handle the issues of MFA (made for AdSense sites) and similar sites - not that all those sites terminated by Yahoo! were MFAs.
Will concludes that "maintaining the quality of our Network is vital to the success of everyone involved." I cannot agree more. Nice work Yahoo!
