I have a question about whether there are any "universal unwritten rules" about tw. Codes that everyone follows out of sportsmanship. I just started after years of absence and don't want to get people more pissed off at me than normal.

things like cordoning off SD, blowing up class 0 ports, defending your home planet with nav haz, blowing up new players, camping at the stardock, taking out a corporation's assets within the first few days, attacking blue corps if you are blue, etc. some of it seems to be a little too sneaky to be globally acceptable. are there any unwritten rules about these or anything else?

thanks
