+Abuse reports form a foundational part of internet infrastructure. The ability
+to get in contact with a person responsible for IP address routing or machines
+involved in an ongoing attack in a timely manner is critical for internet
+stability and operational security.
+
+Sadly, some junior administrators have decided that standard internet
+background noise constitutes critical abuse behavior and automates sending
+abuse emails in response. This floods abuse inboxes and makes the global abuse
+reporting system less real time and, thus, less able to respond to actual
+attacks.
+
+Worse, these automated abuse senders rarely respond to follow-up or requests
+for more information, making it clear they don't actually care about the
+"abuse", they just want to send spam.
+
+To combat this, we completely block any automated abuse senders after several
+attempts to reach out and resolve the issue if we receive no response. Further,
+we block all messages coming from common auto-mailers. The two files in this
+directory are regex lists compatible with postfix's `header_checks` and
+`body_checks` configuration options, and should block most spammers who hit
+abuse inboxes.
