XF 2.1 Silly question about Q&A CAPTCHA

[frm]

I would test it myself but I've exhausted all emails to do so on my live site and have yet to set up a test server.

Are Q&A CAPTCHAs case sensitive?

Question: What is the country with the Tokyo Tower?

Do I just need to put Japan and will only Japan work or can users get by with japan, JAPAN, etc.? Or do I need to add all iterations as well?

They're case insensitive (any will work).
