Can the admins give us a definitive green message on pursuits that can be added into the rules?
I remember once an admin said it was ok to start an encounter (piracy/fight/whatever) in a system your ID permits and to chase them into system your ID does not permit, however that seems to have changed as this happened meaning that the circumstances can differ.
I think it's pretty clear. You cannot make a demand in House Space, but if you made the demand outside of House Space you may pursue the target into House Space.
It's not a sanction there, it's a warning to not cross the thin line between the two situations.
