In one-key scheme you, the encryptor, would also have to encrypt the naughty word list, allowing you to cheat, so it will not be allowed.

Ahh interesting. So you could not have one key encrypting the messages than a separate org-wide key encrypting the naughty word list. That makes sense. Thanks.

I think there are some multi-key schemes but they are much more expensive and very rarely used, I don't know much about them
