Communicating Conspirators

Alice delegates Power to Bob. Alice does not want Mallet to have Power. Can Alice prevent that? Nope!

An ACL system will gladly let you express that Mallet may not access Power but it's completely unenforceable. ACLs provide a false sense of security in this regard.

Screenshot from the "Communicating Conspirators" page on erights.org:

"Bob and Mallet are properly in communication, and Bob and Mallet both wish Mallet to have the power. They are Communicating Conspirators. Can Alice arrange to prevent Bob from giving Mallet the Power? The answer is simply no. Bob can circumvent any such attempt by creating a message laundry."
