I have mixed feelings about it staying -agree with both your reasons and would add a third, that it shows this pathetic, scheming conman as exactly the leech and liar he is - but in the "against" corner:
1. Websites with good intentions should not give convicted criminals a platform to beg and/or use deception to attract sympathy/money
2. While it is allowed to stay there is always a chance that some secret millionaire liberal might be taken in by it and pay it.
The escalating debt, moving further and further from the possibility of him ever being able to pay it is my preferred option. Fethiye deserves that.
