Hopefully your account recovers soon. Many publishers have gone through the same experience and eventually returned to normal without violating any policies.
I dealt with this a few months ago. Instead of searching for shortcuts, I focused on improving my site's content and making sure all my traffic was genuine. The limit was removed after about five weeks.
My biggest mistake was checking the AdSense dashboard every hour. Once I stopped worrying and concentrated on growing my site, things eventually sorted themselves out.
