A WebmasterWorld thread reports seeing weird "property info" within their Google AdSense account settings page.
The information includes:
AdSense for Content: ca-pub-#*$!#*$!#*$!#*$!#*$!XX
AdSense for Content Host: ca-#*$!#*$!#*$!#*$!#*$!XX
AdSense for Search: partner-pub-#*$!#*$!#*$!#*$!#*$!XX
AdSense for Search Host: partner-pub-#*$!#*$!#*$!#*$!#*$!XX
Referrals: ca-ref-pub-#*$!#*$!#*$!#*$!#*$!XX
Referrals Host: ca-ref-pub-#*$!#*$!#*$!#*$!#*$!XX
These results come from the AdSense API and Google's AdSenseAdvisor explained there is a bug in reporting.
Our AdSense API team tells me that the AdSense Host properties that some publishers are seeing in their accounts are being shown in error. These ID numbers are are used for websites that have implemented the AdSense API.Our engineering teams are working to investigate and resolve the issue. In the meantime, know that there have been no actual changes to the affected accounts, and no action is needed on your part. Sorry for any confusion.
