These places have the barest level of accountability possible, they'll never police it like that.

You'd have better luck using their lack of oversight against them, put up your most convincing spoof "support fund" collection ASAP and quietly organize a mass report of the alternatives to become the de facto leader. You probably won't be able to keep up the charade long enough to cash out, clean it up, and quietly slip the money to the actual victims/family, but hopefully it would last long enough to kill the PR inertia and vastly reduce the amount of blood money the criminals eventually gather.
