Why can't I delete some of my IOUs?

IOUs can not be deleted 10 days after they have been entered. This restriction helps avoid confusion for transactions that are old enough to be accepted by all participants as correct. If you made a wrong entry, it's very likely to be noticed within 10 days. If not, it's highly recommended you add a new transaction to correct the difference, instead of deleting the old one.

Being able to delete transactions that are too old is prone to abuse by people who want to mess up other's balances, and hence we do not allow it.
