I agree with Jinx - and as an Indie "capwhore" i've had a bad feeling about these faction enforced embargo's that are not in the rules.
If it is now rules that server factions can control who buys what in terms on capships then this needs to be listed in black and white in the official server rules in idiot-proof print so that this issue can be put to bed.
All we have on this issue is some posts by a couple of admins in threads that a new player will never find.
This also opens another question - can a single admin just add a rule in a thread that is not in the official server rules and then have those rules be considered "official" and binding? If so, fair enough....
But according to server rules, strictly speaking, a faction member who opens fire on an "indie" of the same faction is sanctionable... thats what a new guy to the server is going to think.
