Does checbox provide an alternative to using captcha on a website? I think I need to use captcha to register users. Instead, if I check the box for terms such as "By clicking here, I agree ..." can this fix the bots or fix the addition to the check box?
One thing you can do with a checkbox is to make a honeypot . To do this, you check the box and hide it using CSS (because bots, as a rule, don't care about CSS). If checked, then this is probably a bot.

In the end, this should work fine until someone finds the time to target your site or system.
