I have been thinking all night about a possible solution to this predicament and with my limited knowledge it does point to a consensus mechanism that we will need like Steemcleaners having more power in bringing accounts that scam to negative levels quickly and once that is done should have transfer mechanism turned off. (although I did think how it would affect accounts like Bernie)
We really cannot stand idly by anymore.
Hoping for a solution to appear - it's whitehat theft I guess, with a promise to return the funds.
