Something which may be of value to everyone in this matter would be finding ways to build trust and mathematical understanding of the matter. You should consider creating a simple cron script to keep track of positive liquid assets the exchange makes from all transactions. It would show current total based on the last X transactions, and how much is allocated to paying back losses.

There could then be a breakdown showing where these assets originated (such as Y amount from ABC coin, Z amount from DEF coin, etc), tying it to a public ledger of the past transactions. And if you really wanted to add that Disney Touch(tm), you could  have a goal meter showing what the outstanding balance owed to members is, and when someone visits the page it would show theirs as well (to them..), and even break it out to show (based on fee amount) the volume of BTC trades required to reach the goal (which as we all know, is more than a lifetime's worth).

This gives bottom-to-top accountability of the assets, and without emotion or human interaction, provides a factual up-to-date public accounting for everything, lets people know how much is left, what they have, where their repayment is coming from, and prevents people from easily shaking fingers and complaining. This would help alleviate much of these complaints ... and you would be the first exchange to ever open their books to the public. This is cryptocurrency right? It's about accountability on a public level. Imagine the possibilities if you do this..
