FYI.
Normally, I do not run automatic banning systems, but after reviewing fail2ban again, I see the ban is configured out-of-the-box to only ban for a short period.
So, am testing fail2ban on all my Linux servers.
However, I agree with you stomp, that changing the sshd port from 22 to another value is one of the best deterrents agains these bots.
The same is also true for web software, for example Word Press. The best way to stop bot registrations, bot logins and spam posts is to change the URL of the registration, log in or posting scripts.
Also, having said that, I was hoping not to quickly get into remediation and risk management; but to get more people to post their FLAPM stats; using our simple method, so we could gather more stats.

-i | --ipaddr <IP address>
