You seem to be a nice group of friendly, helpful people. Had some nice roleplay with one of you the other day as well. But, since you asked, here are excerpts from some ramblings I had the other day...
Don't make promises you can't keep.
It may seem obvious, but time and again I've seen people propose to do things as part of a treaty or such that they simply cannot do, that are impossible. Then others will blame you for failing to uphold your part of a bargain, and things will get worse.
You simply cannot stop people from landing on Freeports. Gameplay mechanics outright prevent it. You can shout and read off "laws" till you're blue in the face, but you can't stop them. Going via the admins (FR5,sanction report etc) simply isn't feasable except in very extreme cases, and just creates a negative atmosphere. Public shaming, angry letters and the like on the forum comm channels are just as detrimental. It just leads to bad feelings and bad blood between everyone.
Another important thing to consider: In canon roleplay, Zoner Freeports are open to everyone. Following the precedent of faction rights over independent characters, you cannot order them to override their canon RP with "faction" RP. I think that trying to ban ships from landing on Freeports is the wrong thing to do, would not work, and would just make things much, much worse.
You cannot control what anyone does after they leave a Freeport. You cannot track where they go or who they choose to attack. You have absolutely no way of enforcing any rules preventing ships from using a Freeport as a base from which to attack someone. What's more, in vanilla canon RP, the bounty hunters guild did exactly that. So did many factions. Trying to stop this is most likely futile. Claiming or accepting responsibility for attempting to somehow prevent these attacks would be completely disasterous.
And another thing. Don't claim to represent the citizens of Freeports and don't claim to represent the Zoner community. And for crying out loud, don't try to create any sort of "Zoner government" or related sillyness such as formal Freeport administrators, governors, mayors, councils, commonwealths or coalitions. That isn't the Zoner way, not least because there is no such thing as a "Zoner way", and you know it. Embrace anarchy. It's delicious.
