It's official! AdSense has completely tanked for my account. April 8th earnings go down in the books as my #2 lowest earnings EVER. That's a record AdSense low I never thought I'd see in 2013.
Checking out the Google AdSense Forum shows a lot of threads by people experiencing the same massive drop, so maybe (hopefully!) this is some major reporting mishap that will get straightened out. If not, well it's been nice knowing you!
