Ruling: Kyoji attempting to enter the thread is VALID
After looking at both sites (Gladius and Neo-Gladius) for Kyoji's travel/locations - the last actual travel that was done was on April 6th, returning from Konoha to the Land of Water. Other than the ToW and HE the only IC placement of Kyoji was within Kirigakure since then. Since Jacobi is not on site anymore to ask about any specifics I'm going to assume that the reason that a thread about Kyoji rejoining Kiri was not done was due to inactivity from either or both parties.
As for being able to hunt him, Haruko was not an active Kage, and so I believe that that is more likely the reason arresting him did not occur. Kyoji's last recorded IC position was Kiri, so that's where he is. However, he may not spawn at the gates, he may choose to join from inside Kiri as Chigetsu did.
I would however like to caution against abusing this. I expect to see activity from Kyoji - The Heavenly Emporium and the Theater of War are not to be used as 'safe zones' for missing-nin.
