I'm not oft to repeat myself, but since this keeps popping back up...
Nothing is going to be done about this, and not because FD doesn't want to do anything about, it's not something on their radar, or because it's too hard.
There's simply no way to do anything about it.
If "Oh, you disconnected in an unusual manner" is mete with "Your ship is destroyed, rebuy" there will be an endless flood of support issues for legitimate disconnection caused by power failures, ISP failures, even cats sitting on surge suppressors and turning them off - all things outside of the player's control that resulted in an unwarranted ship destruction. So this option is pure fail.
Flagging people for the same reason is also pure fail, because connection issues and power faults do happen.
The ONLY real, viable "solution" to this is:
Suck it up and deal with it, you're not getting your way.
I know, that's not the answer PvP folk want to hear, but it is the only answer. You might as well open a poll to have grass turned blue, or water to freeze at 70 degrees, because these are more realistic to happen.
The only other option would be to eliminate the insurance rebuy and all losses for combat destruction, and then no one would care and wouldn't disconnect, because all that would happen is that they end up back where they last docked, and PvP would die because there would no longer be any real incentive for it - there's no more "thrill" of costing someone potentially all they have and forcing them to start over to satisfy yourselves.
Is that what you really want?
