1. get an IT specialist to check the IP of the one who posted that utter rubbish about you
2. if you can trace that rubbish to her, you have a solid case and thus call a laywer NOW.
3. if you can't trace any way that she did that to you, still call a lawyer NOW.
Why wait? Seriously. Call, do action. It takes years to build a reputation, the moment 'smearing' starts on the internet it takes forever to erase it. So please act
