I thought we've all moved to sftp + fail2ban…
ftp??? wow hasn't that been deprecated for decades now, along with telnet???
Not exactly the same. There's a huge number of people out there that still use FTP, including many "professional" web developers.
I beat my head against this for years, trying to educate the world, then gave up.
I provide FTP access on request (i.e., enable it for an account) and allow only designated IPs / net ranges (iptables). Failed connection attempts are logged so I can easily see what's going on.
