I just argue that Captcha isn't one of them. Here's something to consider, natural language processing. A machine smart enough to create these complicated captchas is potentially smart enough to understand and distinguish people's comments from spam. It's doable for sure! I say this because I personally created a prototype and from what I can see, it works great (just look at my Qwaider Shield counts and you will know) My rough estimates put the ratio of Spam to real comments at about 20:1 on an active blog. Over the past few years that I've been running my prototype, I ended up flagging 2.8 million IPs for potential spam and it's quickly rising Anyway, I doubt there's a single quick magic potion that will solve this problem, captcha is certainly not doing that great. It helps, but for a very short period of time and against very limited set of attacks Personally, I think removing the value of what the spammer is looking for (a link back) is worse than blocking them from commenting. Simply by disabling comments with links you do way better than any captcha can provide, with a fraction of the effort Hi Mohammad,

But let’s look at the bright side of Captcha, if you cannot do anything to stop Spam then I think that Captcha is the only way to at least reduce spam messages.

If nothing would stop spammer then a technique to reduce spam as much as possible is totally appreciated. to have something is better than having nothing to use.

The problem is that even the toughest captchas are being cracked, not necessarily by bots, but by humans. Yep! That's what many tiny sweat shops in Philippines are doing where captchas are being cracked for 0.02c each or even less. Eventually with these pretty sophisticated captchas it will start taking more computer time to generate than it takes to crack! Then the "bad people" will create a nice big dictionary of all of these and offer it for sale. Captchas are inherently stupid! The whole concept is based on a novel idea that the human brain can comprehend better than machines, which is wishful thinking at best. Add to that the inherent problems associated with this specific test and people with disabilities, visual or otherwise and you will end up with the simple conclusion that captchas are -by design- stupid and no matter how sophisticated they are, will end up in the garbage with the rest of the useless crap Although this is a neat technique, I doubt it will stop spam when it really matters!
