Basically since there is no other way of getting up there -- even if you're a parkour god -- other than teleporting on top from the T room, does it make it a traitorous act? There's no way to propsurf on nuketown as there are no props. Spoiler both players on top of the roof here were Ts
I am almost positive that the roof of the yellow house on that map is a traitor-only area accessible only to traitors.
The last discussion we had as staff regarding this, it was deemed a traitor only area. This would fall under the following traitorous acts: 10. BEING IN A TRAITOR ONLY AREA 1. Includes entering and exiting. 2. Holding/blocking open traitor room door. If anyone has a legitimate strategy to get up to the roof through standard means we will re-evaluate the location.
