Fail2ban rules to stop naughty use of my servers

This fail2ban configuration is stored here for reference by myself in the future, but anyone is free to take a look at my custom rules.

The rules are highly specific to weird/dodgy traffic I get on my servers. Currently, the biggest "threat" is from a service called "Site24x7", who are constantly barraging my servers with broken requests ("G" requests, not "GET" requests). Sorry, I've got to block you!

Amongst others, there are a lot of attempts at using Wordpress features, or other old fashioned CMSes. As soon as one of these requests come in, block 'em!
