Captcha Me If You Can

So you know how sometimes when you're on a website, you get one of those CAPTCHA's to make sure "you're a human" and not a "computer bot"....? I was on a....well to avoid getting into trouble, let me just refer to it as a "well known social networking website" tonight and when submitting a post, I was prompted with the following Captcha.



It concerns me! Surely, this "well known social networking website" would have procedures in place to stop this happening - you know a "Two words not to put together list". Examples might be;

Muslim & terrorist
Lactose intolerant & cow (OK that's three!)
Britain & sun
iPad & tampon
