so i got this google captcha on my computer (http://ipv6.google.com/sorry/IndexRedirect?continue=http://sorry.google.com/sorry/misc/) the captchas are simple enough, but i tried 10 times and it wont let me pass? i am not even doing anything on my computer, and my computer is not cranking. (i just cleaned it yesterday.) is that link legit? if so, why it wont let me pass?
