As you know, the top roof of the gate, or third floor if you will, isn't somewhere you can just walk up. We only can get up to the second floor on every neutral gates exist. Yet, these guys somehow managed to get up the third floor, setup a forward camp, and directly exploit on the Cyrodiil, where your actions have clear impact on the other players.
So,
1. Fix it
2. Punish those who exploited it
If it is possible, check the log and find out who got up there first / who set the camp first. They are the exploiters.
