I have to agree with Spiky and Wavey on this one.. If you're gonna play in someone else's system, then you better be damned sure you know what the rules are.. and that you follow them..
Unless, of course, you are doing your RP.. in which case, you know you're gonna get into some PvP, which is what the RP is all about. That's to be expected, and you go into it knowing the risk of getting your ass blown up in space.
I have my fair share of Pirate, Smuggler and Merc chars (as being a Freelancer I can
), but if I'm gonna trade in a Clan System, then I'm gonna abide by the rules.
Wavey had no problem giving me permission to trade in Custo, and no one ever bothered me when I was doing it, cause I played by the rules and didn't trade or smuggle any BMG.
I'm sorry the poor dude had to learn the hard way, but it certainly pays to play fair and know what the hell playing fair means in ANY clan system. BG can certainly police their system in whatever way they see fit.. same goes for SMG, SFP, TRF and all the other clans.
I got blown outta the sky just the other week by a TRF who didn't know me.. and just because I was flying in Nephele space. [78]
That was MY mistake.. but you don't see me whining about it on the forums, or deleting the Crossfire mod because of it. [frust]
Afterward, TRF and I had a good laugh about it. No big deal and no hard feelings. 
If this poor dude can't take the heat, then he shouldn't have been smuggling in Custo in the first place. [7]
I certainly hope he will come back when he cools off.. after all, it IS a game.. but I'm feeling at this point that he's being a poor sport about the whole thing.
Jeezuss.. maybe I should send him a block of cheese to go with his W(h)ine.. [103]
