You can use it when you want to send a form (HttpWebRequest), when you have a register system or you can use it as antibruteforcer.

For sending a form you could simply bypass that by sniffing packets with wireshark or a similar tool. As for bruteforcing, you shouldn't hardcode anything 'bruteforceable' in your application.
