+ * This site uses weird type of CAPTCHA. It downloads code from captcha-code.php
+ * and puts it into span tag to display the code. This script extracts the code
+ * with MutationObserver and skips entire download form because its only purpose
+ * is to annoy the user with shitty CAPTCHA. CSS is included to hide the form.
