Has somebody else seen a 'Referrals' row in the Adsense stats? Maybe this means they're integrating it back into Adsense? It always says 'No data available'...

"Referrals" has never been removed from the reporting interface.

"We will be removing referrals from reporting in February 2009, when it will no longer be possible to earn money with referrals."
