Someone could suggest a system, whereby spelling mistakes are used to encode partial information about a magnet link. One switched pair could give you the position in the magnet-link key, the other switched pair could give you the value. That way, you could never pin down exactly who gave you what information. Or maybe I shouldn't suggest it?
