without any ongoing wars, most trading factions are neutral to everyone (lawful of course)
all I can think of right now that has some restriction is DSE, samura and kishiro + bristol (though it's a bit weird on last one, won't get into it ) which mostly applies to official factions and some POBs, due to platinum mining which will be escalated into a mini war /blockade in next patch (or so devs said on main discord server )
the only problem was the players who didn't roleplay, which is not solving anything this way, just shifting it to another I'd which is as neutral as IC or any other id
