I've got an offer/plan.

If the debt of the site is smaller than I believe it is, I'd like to offer 1 BTC to Tomos (for files/database), so he covers the biggest part of his personal loss. I'd be buying his entire debt.

Now, if this happened, I would pay 50% (100% of debt if it's less than I think it is) of all debt to the users, so they return back to the site (new domain), and would wipe all databases, so I can rework the reward formulas, remove all the deposit options and try fix what's broken.
