Captcha is only effective at annoying legitimate users. If there is any incentive to do so, bots have no problem bypassing/solving them.

Is this your experience as a sysadmin or a user? As a sysadmin, this is an absurd statement in contradiction of my everyday reality.

There are dozens, if not far more, of captcha solver API's for extremely cheap. Captcha is very shallow bot "security" theater, they just deter the cheapest attempts.

latest greatest versions of captcha are more resilient to these types of services, but it's a cat and mouse game. I would recommend that you, as a sysadmin, learn at least the most basic things about this stuff.

This sort of language is inappropriate and unnecessarily combative.

In any event, no filter screen is perfect. Getting rid of 80% of bot traffic is a good thing, even if you can't rid yourself of 100% of it. You can't let perfect be the enemy of "pretty good."

People use CAPTCHAs because they work--even if imperfectly. Of course, you have to stay on top of the latest implementations.
