The copy of post with questions to KeYCAPTCHA from from"Preventing Spam in phpBB3" thread by Martin Truckenbrodt:

Sorry, please excuse. But your posts are showing me that you don't have any reliable own experience with the administration of bulletin boards. So I think that your posts are not very usefull for phpBB3 using webmasters.
I've defined forum spam by the doors we have to open - or we want to open - for guests (ANONYMOUS) on our boards. I think these are the only one important things we have to think about.
Human spammers can be identified by their ip address, too. Blacklists can be used without any false positives. This is just related to the way how you are using them.
What's the matter with lazy, blind, young, old or disabled users? Should these people be called false positives?
Why does KeyCAPTCHA offer two non-free editions you have to pay for, too? Is the free edition not working good enough?
@stevemaury: For me I will end this discussion now.
Bye Martin

My statement was not about number of spammers but about percentage of manual spam (comments, posts, Email, etc.)

Please note that free KeyCAPTCHA prevents its oursourcing to 3d-party human solvers sweatshops.
The latter is the most massive, cheap and legitimate manual human spammers but they do not directly interact with webresources being spammed (otherwise spam would not have been so massive, cheap and legit business)

This percentage digit is very simple to estimate taking into account:
- the productivity of manual spamming vs. the one with the use of spam bots;
- there is no economical base to order manual context-sensitive spam (since it is few orders more expensive) and nobody will be spamming just from the love to this art

Experience shows that such methods have never been used without false positives.

IP-address blocking will only block innocuous and unexperienced in this gambling humans but not professional bots using very broad network of computers in various countries

These methods are retroactive and are doomed to always lag behind new advancements in spamming techniques.
Besides, they are broadly used by blackhat SEO and criminals to blacklist competitors (again with the use of bots)

If you refer to KeyCAPTCHA then KeyCAPTCHA has handicap button for the color-impaired.

The support for the blind is easily realized but we had no such requests yet and, hence, priorities.
Plz open support ticket with such requests and it will be implemented after we get a few such requests from our users and as soon as we understand that this is broadly required feature.

There is no difference in protection strength between free and fee-based KeyCAPTCHA.

There is only one fee-based service, that is "Personal CAPTCHA"
permitting to create a client his own captchas from his own images with our online designer.

The information on our site about second fee-based service is the error.
That was thought about initially but never practically realized or used.
