If Confed don't like you, it means you've killed too many of their ships, this in turn encourages a 'friendly' disposition from the Kilrathi towards you. Likewise, if you beat up on Merchants, Hunters will (try to) grab the bounties on your head, but Pirates become 'friendly'.
But does this really mean anything to you, Spanky? Sorry, but I can't believe someone would spend so much effort to finish a game only to sell it straight after.
