It has come to my attention that using an audio captcha will allow any
entry to be accepted as correct which, in my mind, is a glaring hole
for a captcha software.

I have removed ReCaptcha from my website in favour of using an actual
captcha that actually prevents automated access.

That was a damn fast fix. Very well done.

I don't believe this is fixed yet.

All you have to do is submit 6 words and it passes every time.

Yeah, this little exploit has completely destroyed certain forums.
1. Click audio reCAPTCHA
2. Type as many or more words than are said
It works every time

Bah, you're right. It failed me on a six and seven word piece. That
said, it must not be very picky, random sentences up in higher ranges
are more likely to pass. Regardless, spam started getting in, I'm
going back to swapping out reCAPTCHA from my sight.

Hi all,

We've pushed a change which fixes the problem with the audio CAPTCHA.
Thanks to everyone who brought it to our attention.

Best,

There seems to have been a regression. The audio captcha is accepting
arbitrary input once again.
