If it's man-controlled it certainly does, like a ballistic missile blocking
device is also security/safety.

In real life security is also an "analog" kind of thing. Something becomes
"more secure". Passwords (at any complexity) always have a chance to be
random guessed, yet they're security. Bottom line security is usually
considered to be something of "added safety".

The foolish thing here was to think it'd really help. Yet other will always
be so foolish to misunderstand what CAPTCHA's mean and meant.
