It’s a game space ship go boom
Only if someone decides to blow it up. Why would you do that? For fun? Your fun?
Ethics is complicated, but to think that sitting behind your computer, playing/interacting with other people, takes away any responsibility on your behalf, is wrong. I know some don't get it. I do not care, and I've learned to defend myself against those. To me they are still jerks. That was what I thought, when I started playing the game, and I still think so. Be nice. Why? Because we all expect others to be nice too.
I don't mind pirates. They are just feeding their kids, and so am I, so I might decide to say "no". I also like PvP in general, but rarely meet someone inviting to a fight these days. Perhaps because I'm not "harmless" no more.
