Hackers don't use their own IP addresses. So a permanent ban is a bad idea. What you're actually banning is an ISP's dynamic IP or a open proxy or a compromised computer. The ban is somewhat effective against a bot, but it is trivial for a human to bypass it. If you manage to ban all of the addresses that the hacker has access to you'll just slow your site to a crawl as it checks all those IPs with every pase load.
Use the autoban to ban the IP for a day to slow down the bots, convert to a permanent ban for IPs that are autobanned multiple times.
You can slow them down, you may even annoy them (I like to think so). But you CAN'T stop them. The only damage the 404s are doing is to your blood pressure.
Now to your settings, your autoban should trigger when the same IP hits your site twice within an hour. If the bot is timed to reuse the IP after 61 minutes, it won't trigger the ban.
