I am shocked this happened once again! Just a month ago, Google messed up and paid out Indian based AdSense publishers the wrong amount, a lesser amount, due to exchange rate conversion issues. Yes, they went back and paid the difference to those publishers, but now I am hearing new reports of these same Indian based publishers being paid the wrong amount again!
A WebmasterWorld and Google Groups thread reports Google is paying out a 1:1 rate of the US dollar to the Indian Rupee. Yes, the current exchange rate is $1 US to 49.660 INR - again, major difference.
So this is the fourth time, that I found, Google messing up paying their publishers. First time was with Australian publishers back in December 2007, then with Canadian publishers in early September (August pay period), then with Indian publishers last month and now again with Indian publishers.
This might be just a reporting glitch but it is a major scare for publishers to see something like this, yet again! What happened to three strikes and you are out?
Update: They have fixed the issue, and have used the rate of 49.780 : 1, which is reported the "highest ever."
