Dear Air France, After filling in your Web form for a refund of my flight ticket, your infrastructure generated an e-mail to this domain which was then promptly bounced back to me since you failed to register it. I then spend 1h listening to bad quality music in your support hotline, before giving up. As you failed to register this domain, I registered it for you. Once you have processed my support request we can discuss me not forwarding all received emails to CNIL anymore. Have a good day! Christian

I'm willing to bet the guy who did that, did it to humour this crowd rather than for Air France and his support ticket. Otherwise it wouldn't make any sense for it to be written in English, considering he's quite obviously French [1].

[1]

    - *one hour* is written as « 1h ».
    - He uses one space after ever punctuation mark, including commas.
    - He knows what CNIL is.
    - He uses Air France.

btw CNIL is the french national data protection authority https://en.wikipedia.org/wiki/Commission_nationale_de_l%27in...
