Google AdSense. This morning at 2:00 AM, when I couldn’t sleep, I thought, “hey, what the heck, I’m going to look at the front of my site and see if any ads are showing up. Probably not, but I can’t sleep so…”
And I go to the site and LO AND BEHOLD, THERE ARE ADS! And lots of them! Oh, good. Whatever that I had holding my account up has been released and ad revenue can start coming in, slowly but surely. 10 hours later, I go to check and… nothing. They’re gone again.
Google, WHAT THE HELL IS YOUR PROBLEM?!
