I doubt there would be a module on Unreal's site (or even one recommended) that disabled the /module command.
The /module command is enabled by default, for a reason. If you load a spy module, the user has a right to know. If you disable this, you are hiding this fact from them, and, if you do not tell them that you are logging all conversations, you may be in breach of several international laws.
I therefore doubt that anyone would post a module which does this, and I can foresee a moderator coming along and locking this thread soon
