Autmatic blocking of bad IP's

Hey there!

I was wandering does a plugin exist that automaticly bans known bad IP’s from your site, from a public list like http://www.projecthoneypot.org/list_of_ips.php ? Kinda having about 5k visitors per day that are trying to spam, askimet and Better WP Securty do their job but the bots still cause quite the traffic problem so I would like to band them before, they even load the site.

Cheers
