I'm not trying to impress you, i'm trying to make sure anyone who uses
this script is aware of the security implications of doing so, this
list is called FULL-DISCLOSURE, which is exactly what i'm doing.

Yes you could be wrong, how long would it have taken to type man lastb
and check? it lists failed login attempts, which is exactly what you
want.

Are you on the correct mailing list? this list is for the disclosure
of security vulnerabilities, I think adding arbitrary firewall rules
to someone elses machine is a security issue worthy of disclosure by
anyone's standards.
