This is true. However, if CAPTCHAS stop the bulk of casual hacking
attempts because the simple hacking scripts just flag that site as not
worth the effort and move onto the next, then the site manager has to
deal with far fewer true hacking attempts (those which are determined to
get in or hurt your web site).

It is better to have a tent with holes in the screen door than no screen
door. If the damaged screen door still prevents 90% of mosquitoes from
getting in, it does let you chase down and kill those that do get in.

Just because a security technique is not bullet proof does not mean it
isn't useful.
