When I privateered, the second time, as Bowex (not the first time in group with the QCP) I always went to the trouble to explain to whom I was pirating, in RP, that I was doing this as a service, to make sure they were aware that Kusari was not safe, and that Bretonia was a much nicer place.
Same thing, but helps avoid going ooc.
I'd like to add that using the Tradelanes and Gates actually does, in deep rp, drop credits into Samura's pockets, hence, even passing through, does benefit Kusari.
People arguing that this hurts other regions need to open up to the fact that the jingo-nationalists of Bretonia don't care, at all, about anyone but home and hearth. Lanzerotte is not such, nor is Kusari, Rhineland, or Liberty.
