Thank you very much for helping all those she stole from + me out. The artthief was removed from Facebook and I've recieved a message from Facebook stating just that, so she didn't delete her account out of her own accord. All posts involving her are gone, too.
By the way - I have an insurance. I could hire a laywer should I need one and since I live in Berlin, finding one is a matter of a few phonecalls and a short trip with Berlin's excellent public transit. Just saying
