Repeated offenses by the same client address will accrue greater
penalties, up to a configurable maximum. A PerSourcePenaltyExemptList
option allows certain address ranges to be exempt from all penalties.

We hope these options will make it significantly more difficult for
attackers to find accounts with weak/guessable passwords or exploit
bugs in sshd(8) itself.

Nice rate limiting

In the old days we called it tar pitting.

Tell me in the old days there were other things that could happen. Like feathering somebody after tar pitting. I dont know what that would've meant. Maybe servers ridiculing an attacker or something.

Tar pitting sounds way more fun than rate limiting >.>

Could be a feature where servers would add your IP to a list, and send it to the clients (like a list somewhere in case of a website)

Then clients would start sending random metasploit-esk requests to those IPS
