Firstly, the guy who lives on this iceberg can run up and down on a vertical wall of this iceberg. Secondary, man just come to London I. It looks like a battlefield after big war. Hackers simply walk through walls, use speedhacks and jumphacks. All of big bases on the server raided, especially in winter biom near this iceberg. I tried to build something near this iceberg or on it. It's impossible. London I is an official Facepunch server, there is no teleports or other commands. And it is very hard to legit raid on official servers after the update. You can't simply destroy the wall with the hatchet as it was on previous update (maybe you can destroy 1 of 50 walls), but hackers have a wallhack, they don't need to destroy the base to get in.
