    I use fail2ban for 2 main reasons. The first is to automatically ban people trying to hack into the system by stopping IP traffic for a given time after a number of failed login attempts. I also use it to reduce load on RBL servers by blocking IP addresses that are returned by a RBL. This means an IP address will never be checked twice.

    The best way to block those nasty bots and spammer. It's amazingly easy to configure and deploy.
