Of course, running with the RM/LN example, the RM is classified as an unlawful entity in Liberty's borders. Same for KNF/BAF. I used to collect on KNF all the time in my Bretonian BHG, as long as it was in Leeds it was OK. At least, that's what I've heard. Whether it's against the rules are not isn't really important, it's whether or not in-RP you'd wanna collect on the bounties and run the risk of potential ramifications for the Guild as a whole (say, you space a few too many RM, and all of the sudden the BHG is getting some cold treatment in Rheinland).
