Tired of fighting against SPAM bots that automatically register to your
phpBB forum despite visual
confirmation already enabled?
Here's the solution:
phpBB with KittenAuth support for visual
confirmation, replacing the
CAPTCHA
based visual confirmation of the current phpBB 2.0.20 (which can be
bypassed by automated SPAM software using
OCR
algorithms).
This is nearly a reference implementation of a cool idea by
Oli Warner
that was first published in his blog article
The Cutest Human-Test: KittenAuth.
I implemented his idea with some
modifications which make it very easy to flexible respond to spammers
even if they try to bypass the KittenAuth visual confirmation: You can not
only change all images to your personal liking very easily, but there are
also different kinds of easily adjustable questions regarding the same images,
requiring the user to select different images for each question!
This will make it especially hard for automated systems to pass by!
The result is
phpBB KittenAuth 0.9.0! You can check it out immediately
at my
phpBB KittenAuth Test Forum -- just try to register there and see
phpBB with KittenAuth in action!
I already use
phpBB KittenAuth for the
Rocks'n'Diamonds Forum
with great success! With the normal, CAPTCHA based visual confirmation,
I had to delete at least two or three automatically registered SPAM users
per day -- since I use my new
phpBB KittenAuth, I had no single SPAM
user anymore! (Please do not use this forum for testing KittenAuth, even
though it is even harder to register there as an "outsider", because I used
images and questions that require a little knowledge of the game itself!)
If you also want this for your phpBB forum, just go to the
Download section and select from various
pre-packaged archives from which one will suit your needs! The installation
is very easy even for a heavily modded phpBB and won't take much more than
ten minutes! Try it out!

phpBB KittenAuth,
