Has there been any serious talk of her getting fined? I was just reading this article that mentions the possibility:

Says she could be fined $10,000 if they choose to enforce the guidelines in the WTA rule book.
If I recall, the prize money for making the semi's is $500,000. Make the finals and you have $1.2 million if you lose and $2.4 million if you win. I think that Azarenka would gladly have agreed to pay $10k for being able to take the MTO.
