My guess is that if your target visitors are Teens then you are in bad luck as most teenagers are out there in USA giving their mid terms and in Australia giving their finals around this time of the year. Give it some time and it will jump right back up with your other winnings.
Actually, Mine were way up today. It was one of my better days in 2 months. hope it works out for you.. Da-Chief
Mine was up.. I was shocked at the ecpm today.. There was a 10 and 8.. I am not talking about small traffic either.. Over the board there was an increase.. I have been checking the stats every half an hour since the PR crackdown on many sites ( None of mine though), for fear of a crackdown on ranking too.. Not that I even mention TLA once OOPPS: Sorry. I am not a YPN publisher. Adsense..
