Bad Behavior is a set of PHP scripts which prevents spambots from accessing your site by analyzing their actual HTTP requests and comparing them to profiles from known spambots. It goes far beyond User-Agent and Referer, however. Bad Behavior is available for several PHP-based software packages, and also can be integrated in seconds into any PHP script. (quote from the [[http://www.bad-behavior.ioerror.us/ | homepage]]).

====Integration in wikka====

=== Bad-Behavior 1.2.x series ===
''these instructions are for version 1.2.1 but should work for the whole 1.2.x series''

~1. [[http://www.ioerror.us/software/bad-behavior/bad-behavior-download/ | download]] it
~2. unzip the file, go into the folder and make the following changes:
~3. add ##bad-behavior-wikkawiki.php## to the folder, with the following content:

~5. upload the whole folder to ##3rdparty/plugins/bad-behavior/##

%%(php)
//load 'bad-behavior'

add %%(php)

// note: this is a it's-working-for-me, i.e. an alpha version.//


~1. [[http://www.bad-behavior.ioerror.us/download/ | download it]]

~2. extract the zip-file and upload the content of the **subfolder** bad-behavior (i.e from admin.inc.php to whitelist.inc.php) to **3rdparty/plugins/bad-behavior**

~3. Add the following file as ##bad-behavior-wikkawiki.php## to the same folder:

== Issues ==
- no config-options yet.
- it probably breaks with mode-rewrite=off
- not all of the functions are finished (they require some changes which would be better located in the core), but none of these is used (at least in 2.0.10)
- I should take a look at the version from Mike (see comments below)
