I know the professor who created CAPTCHAs fairly well (did research with him) and I can say that these captcha's are missing the point of captcha's.

The hard to read word is there to prevent spammers. With easy to read words, you have a limited number of words per a page. In the end, the probability that a program randomly guessing the assortment of words (O(n^2) combinations if we assume order) is actually quite high.

So you replace the hard to read CAPTCHAs with easy to read ads. Of which presumably there will be a limited number in circulation at any one time. Sounds kinda easy to circumvent...

You know, most modern capchas are not solved by bots, but by people in third world countries solving them for pennies. The current going rate is about $1/1000 and there are easy to use captcha solving APIs for any platform. capcha has long provided an illusion of security, nothing more. Any and all captchas will be broken.

I know the founders of reCaptcha. This is easier to prevent than you think. Its also quite rare.

I don't often hope for entrepreneurs to fail, but I think this is a place where they are actually making the world worse. Not only do they completely fail at what they are trying to do (ie: prevent spam), but they do so in the most possibly annoying way.

I'll gladly contribute my time towards writing browser extensions to hide and automatically solve these things if they take off.

I'll be happy with anything other than today's captcha solution. These are some captchas from my hall of fame: http://www.twitpic.com/2qbv0e/full

Those CAPTCHAs really aren't that bad. If I understand how ReCAPTCHA works, you only need to get one of the words correct.

You know that, I know that, but if everybody knows that you only have to enter the easier-to-read semi-nonsense word then ReCAPTCHA itself doesn't work so well for its larger purpose.

And if you don't know that, then giving someone a CAPTCHA with Hebrew or a Rorschach inkblot in it when they're trying to buy Yo Gabba Gabba Live tickets for their four-year old is a surreal enough experience to make people think they're living in a situation comedy.

It seems to me that they're not attempting to prevent spam, they're merely trying to monetize what has become the standard practice of entering CAPTCHAs. going with something like this it's trading in spam prevention for cash. The legitimate users already expect to see a CAPTCHA, but you're using it for a different purpose

A longtime standing solution to hard-to-read captchas are easy to read (but hard to process) captchas. E.g. show a picture of an animal or a shape and ask what it is, or even just ask a simple math problem or riddle in writing. Problem with those are that they need to be constantly updated from a reliable source, or else, once the solution becomes popular, the spammer can bruteforce it in linear time (no matter how h…

Your argument is somewhat flawed from a technical level as Olegk mentioned, but also from a business marketing stand-point.

Specific ads may be in circulation for a short time, or there may be many running concurrently, but it is the message that the advertiser is trying to get across, the tagline, and it would be of most benefit to the advertiser to get the user to associate their brand with a single concept. Using the example in the article, Subaru may want to be associated with "outback", not "four wheel drive" or "comfy" or "sporty". Businesses who try to target too many things or too wide an audience end up not getting their message across.

I'm not saying that what Solve Media is trying to do isn't a great idea. I think it has lots of potential, but they clearly still have more to work on.
