+# This requires querycontact ( http://pypi.python.org/pypi/querycontacts/ )

+# This uses the https://abusix.com/contactdb.html to lookup abuse contacts.

+# XARF is a specification for sending a formatted response
+# for non-messaging based abuse including:
+#
+# Login-Attack, Malware-Attack, Fraud (Phishing, etc.), Info DNSBL
