This add-on (also known as implementation of CAPTCHA ("Completely Automated Public Turing test to tell Computers and Humans Apart"), or reverse Turing test) stands for a must-have thing for your forums in our automated spam era. The method used here is by now the most effective protection against the spam / flood / robot programs, which still appear being too weak to recognize even the simple combination of the letters and digits typed on the graphical picture.

I'm so bothered to prove to robots that I am not a robot

Bothered to prove to robots that you are not a robot?.. We offer a solution which keeps your constant right to think you're a human. The codes this add-on generates, are simply to recognize and there are no difficult puzzles to solve; still these codes are not simple to recognize by bots.

How It Works

CAPTCHA protection code is often available in the posting form itself, but for miniBB it would be a bad approach, because it includes the posting forms in the topic listings and thread listings themselves, and these pages are the most often loaded. On the other hand, generating the Human Code image always takes additional resources from your server, which preferrably must be kept for the other tasks. Concluding the above said, this add-on asks for a CAPTCHA code only when it's required. For example, if there is a CAPTCHA protection for replies, the user will be asked to enter the code only after he posted the message; if there is a protection for sign-up process, the user will be asked to enter the CAPTCHA code before he fills up the form. This method allows to run this add-on independantly from the forums, and still keeps all processed data safe. The most important, it saves up your server's resources that way, which is specially significant when forums run on a small shared hosting. The add-on also protects such external miniBB plugins like File Bank, Polls or Direct Email.

How It Looks

There's a red line between the hard-to-guess CAPTCHA, which is formally strong, and the obvious CAPTCHA, which is easy-to-guess visually, but keeps the powerful level of protection inside of its code.

Keeping the right balance between the power of protection vs. usability is very important — as you have noticed, often on many large websites the CAPCTHA codes are hard-to-guess even by a normal human; this could cause visitors get turned off from your page immediately.

Check some astonishing examples from a worldwide-known CAPCTHA mechanism. Forget about Traffic Lights, Cars, Bicycles... how about solving this?

Amazing Features

Configuring this add-on you may protect the forums from any kind of the automated attacks:

  • you may enable CAPTCHA for all guest postings (new topics and replies), if your forums are opened for guests - for a better comfort, it is required to enter the code only once, and post without re-asking it until the browser is closed;
  • you may enable CAPTCHA for the new profile registrations - here the code will be reset each time after the successful profile registration;
  • you may enable CAPTCHA for the search function;
  • you may enable to force users to enter the CAPTCHA code each time when it's required, so the code is constantly being reset;
  • you also may enable CAPTCHA for registered and logged users, which have not made specified amount of postings.

On the miniBB community we have enabled the two first options described, and so far we have no more spam, despite our forums are opened for guests. Our own forums is the best example of what this add-on does.

Additionally it's possible to configure the auto-generated image at a very custom level, specifying the set of characters displayed, characters amount (5 by default), True Type fonts used, font sizes, font colors, background color of the image (incl. making it the same as your webform's background - so the CAPTCHA code displayed looks organic to your website), overlapping distance between chars, width and height of the image, grid's step parameters. Despite the script generates a completely random image each time when the code is offered to enter, all listed above could make your CAPTCHA code even more unique, and so impossible to analyze by a robot, despite it would be very easy to read and recognized by regular visitors.

Special Requirements

Before buying/installing this add-on, you must be sure that your PHP version is compiled with, and supports:

  • GD Library (for generating images; most preferrably it should have a version higher than 2.x.)
  • FreeType library (for manipulating the text in the image)

Almost every hosting provider gives an opportunity to use these libraries; but make sure they are accessible on your server before the installation.
