Hi!

"Unbreakable" captchas are broken by social engineering these days. There are a number of "free download" and porn sites out there that "proxy" these captches and let users solve them to get to the content. 

If you have enough solved captchas, you can try and use them as data set to teach/verify some automatic algorithm like a neural net. (In automatic mode, if it only works 1% of the time, it's enough...)

As far as we (msch and I) can tell, there has already been a captcha in 
place since at least mid november. Doesn't seem to do much. Got ideas? hop

captchas are automatically cracked these days..
i'd suggest to implement the raumzeitlabor time thing or something 
similar that needs a certain understanding of the language + human 
skills to figure it out..
i saw a kitten captcha once..
there were 20 kittens and one puppy.. you click the puppy you get in.. 
something like this..
