Lot of words to write about something that has been happening for literally decades. You'll learn to ignore it like everyone else and just move on. Or even better, set up fail2ban with the recidive jail to at least reduce the size of your daily server report email.

Often enough to switch to a different port to drastically cut down the noise, most bots probe the defaults.

I found it interesting. The part about the scripts trying "sheep" as the username was new to me. Not everybody knows everything, so it's nice to read a little article about new things

I found it interesting but a honeypot would have been interesting -- how long do they spend trying passwords for example.

I got tired of dealing with SSH knocks and blocked the port for all external IPs, using WireGuard to get into the LAN.

WireGuard is nice because, unlike most other services, it operates on UDP and sends no reply packet unless you know the key, so attackers can't discover it by portscanning.
