The problem is that the game being so instanced, all the griefers could be in one victim's instance while all the vigilantes were in another. It just won't work unless the victim is willing to just try to get into another instance.
Oh yeah, the technical nightmare behind any truly comprehensive and cohesive interplay between GOOD and EVIL (ymmv); I'm glad I am not the coder assigned to ever get that working!
To me the fact that people themselves are trying anything at all though, (there's a spate of counter-interdictor build and tactics threads lately for example) feels like a slightly different shade of Elite community than I have seen on this issue in a long time. Seems to me it was a lot of whine but not much engine about CG violence in days past. It's good to see anything in general besides people grousing about it in here.
