I am frequently basing in kingdom with a large group of friends, responsible for bases and tactics like this. Every single night we got a team that logs on, coordinates, and takes us down. Just because you cannot do that, does not mean nobody should be allowed to use set ups like this. Plan something, come up with a tactic. Our raiders literally dropped a c4 and used a hacker to detonate instantly in the portal and fucked us (genius). We have also been accepting feedback from the raiders, how to improve, what their tactics were; they even record their raids in which we watch. Theres really nothing toxic about this in my opinion, I dont see how it differs from other bases. Concept: Enter base grounds and blow through dupe. You can set up a dupe at any door at any base, just because we set one up at kingdom entrance doesn't mean anything. As cobaselic stated, there's already a restricted zone right next to the portal. Hope this clears things up for some folks.
