It has been about five to six months now of us reporting that Google has a bug that holds payments to some publishers. In fact, many publishers have been waiting months to be paid and some seem to still be waiting.
A Google AdSense Help thread has confirmation from Googler, Obair, who is still manually removing the hold status on publisher accounts.
It is sad to see that publishers are still experiencing major slow downs in being paid. In fact, if they don't reach out to Google via the help section, they may never get paid. The issue goes back months and months, but was initially confirmed in January 2009.
