This one was a single entrance so from what you are saying its illegal and ill be sure to enforce. Intention.al trapping zombies via teleported or door to kill them is legal of course?
Errr no, the spot that you described DOES have only one entrance, but it is not a crouch spot entrance, thus it wouldn't be illegal......I've never seen problems with "fishing" as many admins partake in it, so I'm judging trapping is perfectly legitimate....
