They are all victims of economic predators who are allowed to exist because they pay for the laws that protect the predators, not the victims.
Considering today's over the top "security" climate, no ship owned by an invisible and unreachable (not to mention untouchable) owner should be allowed to enter any port outside its flag state.
Until abandoned crews profit more than the predators who pocketed the money and walked away, this will continue. It is way past time to make it more painful for them than the crews.
Animals have more protection under the laws of most "civilized" nations than mariners. If you starve a horse or dog you can go to jail ... do the same to a ship's crew and you just start another shipping company.
I can't post what I really think should be done to the owners of those ships ...
