The New Captcha? (irb.hr)

What? The apparently LaTeX-generated strings aren't even wiggled, embossed with some 3d kind of style, or anything. It can be probably really easy to transcribe it back to text and solve easily.

If they're trying to make their captcha as hard as possible to crack (and as hard as possible for others to actually solve it), they should have taken a cue from Rapidshare, with something like "For numbers with cats next to them, take the natural log of that number in place of the number itself."


The first time I saw this it actually was intended to get users to not sign up. It was some "you have to be this smart to join our club" type thing. A reverse captcha? One not worried about computers registering, but instead trying to filter actual users out?

Oh, and I've gotten that Rapidshare thing a few times. It seriously confused the hell out of me. It looked like all the numbers had cats on them, but it only let me type (less than the amount of characters). Do the other letters have dogs on them or something?


Yeah, the rest were dogs. There's probably about a difference of six pixels or something.


not the first time I've seen math captcha but this is definitely a good way to get people not to sign up.


What's with all the Captcha stories? Any funny business going on?


There was an initial post about Captchas and that one linked to a few others. This is how the usual flavor of the moment on YC comes about.

You see the same phenomenon in blogs where you have a few bloggers all blogging about similar toptics at the same time.


Affectionally called "the echo-chamber effect".
