Wasn't margin calls supposed to prevent this?
It is exactly for this, but for the beginning period we had it was not possible to forcefully buy 14k of BUZ2 contracts. There just were not enough sellers. And for this bad moment I listed two solutions above.
According to your page on "Margin Call", that should have resulted in the "worst case scenario", forcibly closing the positions
at that time. Clearly, some people would have lost part of their profit at the time, but that was part of the deal, you had stated that clearly on your page. By not closing them at the time, you took the risk that their accounts would go negative - or did you hope that the rate would change, solving the problem in time, and instead the reverse happened? In that case, you chose to risk your own money, in my opinion.
