Hackers do not use their own IP addresses. So when you blacklist an IP address, you are really blocking a proxy server or an innocent bystander with an infected computer. The hacker just moves on to the next address in his list of compromised computers. That is why the auto ban function releases the ban after a period of time, it allows the real owner of the IP address to visit your site after the hacker stops using it.
Most of these attacks come from unattended bots just going from one IP to the next trying various vulnerabilities to see if they can find a site that is using old software. You still see bots trying the JCE bug from Joomla! 1.5 or WordPress bugs tried on Joomla! sites. The hacker really does not care if it fails, it is just a bot. If the bot finds one that works, then the human gets involved.
