Block anyone who murders you in cold blood for no reason, anarchy systems notwithstanding (there anything goes). In the griefer's reality, they killed you - dead is dead and you are gone. In your reality, the system's security forces locked up the serial killer / terrorist for a long, long time. Yes, you'll have to eat a few rebuys (I think it's fair to let everyone kill you just once), but eventually the ratio of psychotic clowns to civilized pilots will adjust itself to a much more natural and realistic (and enjoyable) environment.I shall read the post about surviving the gank, but I feel that that will not apply to new players coming in.
Until then, solo or private group thanks.
I've been practicing this method for awhile. It works!
