I think on the whole this is a nice approach, however what happens when Mystic
accidentally blacklists your own IP, or it'self? Then you have iptables
blocking you out and you won't be able to get back in =)

Can you modify that to only block on the ports you have for telnet/ssh to the
BBS (assuming SSH to the bbs is different to SSH to the cli).
