Mysterious $message in Facebook notification emails

It might seem like a silly question but I'm wondering why on earth there is a hidden $message inside the notification emails that are sent by Facebook when a friend of yours has updated his/her status.

If you've never noticed it, inspect the source code of these emails and you'll find this:

<span style="color:#ffffff; display:none!important; font-size:1px">$message</span>

This piece of code is obviously harmless but it still pollutes the email preview before opening it. I guess it is a small glitch in the email generation process, probably inside a PHP function that contains a $message variable.

Does anyone know more about it?



Most likely a bug of some kind. Inspect the email headers and backtrace the IP, if the IP is registered on Facebook it's all good. Otherwise report it to FB :)
