If your answer is yes, then simply stop offering any repairs, to any person. Yes, even those people in your linkshell (that you know and love). I would simply say that you are expressing your opinion in a non-violent way. There is no law that says you must repair people's gear. There is an NPC that can repair gear, and people can raise their craft and repair it themselves if they so desire.
Wow, someone takes this game way too seriously.
