Does that make sense ?
Yes, it's called blacklisting, it never ends, waste of time, always chasing new user agents that come endlessly daily, not to mention the fact that some bots use random gibberish UAs, and the size of the never ending Apache script slows down your server.
Whitelisting is the only way to stop the insanity.
You allow all your favorite bots (google,slurp,bing), allow legit browsers and smart phones, everything else gets bounced, done. Apache script is minuscule by comparison to blacklisting, server runs fast as it should and bounces junk to the curb in a blink.
