I sail open public 90% of the time. I have yet to encounter this. If I do the "attackers" will have a rude awakening. I will put him / her / them to the sword myself or scuttle me ship.
My ultimate solution to an unruly crew or crewmen is that I scuttle the ship. I have done so a few times. I announce in crew chat for all hands to abandon ship. I then park and allow my ship to be sunk.
Last time I did this the unruly pirate tp'd off when the ship was about to go down. The crew tp'd back we repaired and finished the material run.
Disney just needs to give us the boot from ship feature, like in svs. With this simple exception to stop abuse: When booted from a public ship the offender marooned gets his / her cut of the plunder if the ship ported at that time.
Then fix boarding privileges and this problem goes away.
