Even so, I don't see that as being particularly damaging and I think they could make a pretty good case for saying they were guessing based on her media appearances, published books, Patreon and 100 hour week. As soon as she threw a tantrum about the claim people started giving her money, so if anything she's benefited from it. I don't know that she'd even win on that point as it's hard to point to any damage it's done to her. As you say the real damage to her reputation would be everything that came out in court.Not legal Frau but I can't see how she can win.
If it is proven she doesn't earn more than the PM, which is probably likely then 'officially' she would win. But hopefully along the way the Patreon tally and the earnings from books and appearances etc would prove that she isn't poor- which would mean she wouldn't really win!
(*I also reckon a tit ton more of her lies would come out along the way! )
If is proven she earns more than the PM...well that would be interesting!
