WordPress › Bad Behavior « WordPress Plugins. I was looking for options to reduce spam from subscribers. I am continuing to search to reduce spammers who try to create accounts to launch spam from. This is another great tool to keep a quality blog.
Ok forget this plugin. I just uninstalled it. Apparently it also blocks helpful bots like MSN/Google so your site won’t be indexed and search traffic will decrease. How disappointing. Instead use Wordfence. It has some great features and even a paid version.
