Questions about using BotBlockX MODX Forums
BotBlockX is a plugin for MODX Revolution that stops bad bots from hammering your site looking for a way to break in and stops scrapers from stealing your content.
BotBlockX is based on Alex Kemps's bot-block.php script bot-block.php. It has been rewritten for MODX Revolution and uses properties for the settings and Tpl chunks for the warning message. An extra penalty for multiple file-not-found hits has been added to help foil hammerers. It does not inhibit well-behaved legitimate search spiders from indexing your site.
