to wrong conclusions. It's awful easy for someone to mistake a conversation about one thing to mean something completely different. Of course that's the reason for code in the first place, to throw people off, but it's easy to think there's code when there isn't.
If words have different meanings in different codes, guessing at what words mean can be hit or miss at best.

Their definition for 'walnut' is quite different than the definition given on that link:
