A Plugin for Joomla 2.5 and Joomla 3.x which includes the Bot-Trap-Script against Spam from bot-trap.de into your Joomla installation.
For the correct function of the plugin you'll need the script from bot-trap.de, which you can get there after a registration and introduction on the forum (Forum in German).
The plugin can also include a black- and/or a whitelist. With these lists you are able to write own blocking or annihilation rules to extend or overwrite the rules of the script.
Please extract the archive first. In there is a readme.txt with installation instructions, a JPG-picture with the parameters of the plugin and two templates for the black- and the whitelist.
