This script blocks those unwanted user agents:
ia_archiver, Wget, EmailSiphon, WebZIP, MSProxy/2.0, EmailWolf,
webbandit, MS FrontPage
To fight all unwanted web crawlers is nearly impossible. See information GoogleBot

To show the result I banned Mozilla/4.0 :-))

Ok, you are not one of those above lousy web crawlers.
You are not using Mozilla/4.0
