I think there's a logic bug/feature where if the rate of attempted captcha solutions from your IP is too high, it won't tell you you've failed (it knows you didn't) but it'll keep giving you more and more captchas. Sometimes I eventually get through after 4, 6, 8 attempts. Maybe because the automated attempts slowed down, or maybe just by chance. Sometimes I end up getting the dreaded "too many automated requests from your network" message (the equivalent of Gandalf's "You Shall Not Pass!") which is fucking wonderful when it's not even google's website I'm trying to access.
