I don't. That's being a carebear. IF you are in Open, you take the risks of Open. This isn't like accidentally being dropped out of hyperspace into the jet cone of a neutron star, or right smack inside a star and instantly overheating to death. Flying in Open, in light or without shields, being unable to properly pilot your vessel and boost at your attacker (popping Chaff incase they are gimballed scrubs or turret noobs) to boost past them while charging up a high wake. Then you deserve to get blasted. While everyone has varying degrees of skill there are modes that accommodate those who wish to avoid PvP such as mobius. Either join Mobius or don't complain when dying in Open. Everyone has options. FDEV restoring data cause someone played in Open in getting destroyed by someone else playing in Open is just unfair. Same with handwavium moving of people who made that neutron jump into a system with no chance of return back due to being isolated.
If you take the risks, you must be ready to suffer the consequences. Heck I even have mercy and pity for those who visit like a Tourist beacon at say, Sag A* where theres no other players.... yet for some reason npcs are all over the place, including pirates, so if you scooped even a tiny little data cache from wreckage or anything... the pirate will kill you for that measley 4k of credits.... even that is meriting a restore of data. But being destroyed by another player in a mode that supports it? nope, no mercy, data lost, dealwithit.jpeg.
Too much carebear demands for Open. You have Mobius, you have Solo... go to one of those and leave Open alone.
