    Introducing a Captcha on a form on my website basically blocked bots 100% of the time. It’s arguably good enough from a practical standpoint.

    If someone really wants to exploit my site, then they will find a way. You can only make it harder but never truly impossible if you don’t want to dispose of all convenience.
