If you go into the bad behaviour folder, look for the blacklist.inc.php file
Open it with wordpad or your prefered editor
There are two sections there for banning user agents, first part is begins with user agents
Second part is, if found anywhere user agents

Ban anywhere user agents are after this code

PHP Code:

    // These user agent strings occur anywhere within the line.
    $bb2_spambots = array( 


Add the following to the found anywhere section

PHP Code:

        "artabus",
        "Deepnet Explorer", 


This mod is so easy to work with on banning or blocking bad user agents
I found this mod cured a problem I have with banning user agents via htaccess

To test if the ban works. Go to Bots vrs Browsers and check on this page

Add the user agents anywhere in the test string and try to view your forum
