We are offering the CAPTCHA from the goodness of our hearts. It would be much easier for us to simply deny you access, so you have to remember that we are just trying to help you.
Solving the CAPTCHA will prove that you are the kind of idiot who thinks you will get temporary access to this web property. But you won't ever get it right. Muhahaha.
If you persist in attempting to access websites anonymously with your so-called Tor Browser, a web browsing interface used exclusively by criminals and terrorists, we will have to report you to the relevant authorities. Scrap that, we've already reported you.
