I wasn't playing a linguistic game. You mentioned standards and malformed requests, and I pointed out that you misused those terms. I am not bothering to track down definitions for you to play, as you say, linguistic games. You are free to find something that proves my position wrong, as I used the RFC to cite my position as correct.

If you meant to put forth that faking a user agent is a technique to exceed authorization, that's fine, and I'm glad to have helped you clarify it. Just be clear, it's not what you said with your detour into malformed requests.
