Well Bart - at one time I would of looked at it as Rep "Stealing" - but after many discussions we've had here on the subject I looked into some of the math behind it and it matters a lot on a) number of players in the area b) number of targets in the area c) number of Crew % Bonus and d) number of kills / respawns. This is why I went to using Rep Distribution, because it really depends on those factors and you can actually get more Rep in different combinations / enemies / locations than just looking at one location / enemy group.
I've even been able to perform tests on some of this recently using Tormenta vs. Outcast (Tormenta being another "hot spot" for those levelling for large Rep). Other locations as well are just as good or better than KH for Nades or Staffs, which is why the focus of Rep Distribution vs. Kingshead Behavoir I see as two different discussions (and we really do have several threads already on Rep - do we need to go off-topic on this one to add another?

As for my viewpoint on KH, I believe general overall politeness usually wins, and when it doesn't I wouldn't want to be there with someone who's rude anyway - and make my exit. I also recommend those trying to level to experiment with other locations besides the obvious - because there are several other locations which return better results for the time spent (and never used).
