Have CAPTCHAs gone slightly too far...?

I like a bit of security just like the next man. But I wonder if this piece of "security" is going slightly too far. It appears that in order to make a posting on Facebook, we are now required to fill in a CAPTCHA consisting of words in two different alphabets...?

Now, I was trying to decide if this was some kind of perverse general knowledge test, or the latest CIA "initiative" to track down terrorists. Mention the wrong keyword and show an ability to type Arabic, and you're suddenly on the list of America's most wanted...?

(Oh, and even if I could have read Arabic, I would have still got stuck with the mysterious blob on the left. Answers to that one a postcard...)
