Exactly, I suffered this landlord abuse while working abroad. Apartment was delivered back to the landlord crystal clean and 100% intact. Then they took my entire deposit and billed me around 12,000 EUR. I even had pictures to show that I had done no damage, but you can imagine how foreigner vs native testimony works in these kinds of super-racist countries. I managed to leave before I had to pay the bill, but I still lost my full deposit. Apparently this "fleece the foreigner" is a well known tactic in some countries.
