Changing Traffic; Any Insight?

Alright above is a graph showing the traffic trend from profile.myspace.com over the last few months. The big dip in the middle is when Myspace blocked traffic to MyBannerMaker.com. After a couple weeks of that, they realized they made a mistake and unblocked it, and traffic went back up. Well, over the last month it's slowly been dropping and right now it's actually lower than when we were completely blocked, but I'm not getting any complaints from Myspace users and when I test, everything seems to be working just fine.

I'm really starting to wonder what's going on here. From what I can ascertain, Myspace hasn't been losing traffic over the same period of time, and nothing that I could imagine altering the click patterns of Myspace users has occurred. I figured I'd put this up and see if any of you might have some clues as to what's going on. It's getting pretty bad, and with the massive toll on ad revenue, decreasing traffic isn't going to help keep the site running and the A/C on this summer.
