Because most of us bought the game to play it and are not cheating idiots? There will always be cheaters, but that’s the exception, not the rule. Besides, people who abused that room will be gone soon, can’t really say I’ll miss them. As for losing all legitimacy, how exactly?
How? Because they have the best weapons/armor/items in the game. And they are selling them to friends. So while you may have built your character without cheating you will/may be up against characters with two shot explosive weapons not legitimately earn.
