It sounds like you made your own CAPTCHA-lite. If it's not a very attractive form to spammers, sounds like that's fine, but for bigger sites it may not be enough. CAPTCHAs don't have to always be squiggly letters... there are many picture-based puzzles these days, along with human-like interaction checks, audio puzzles, logic puzzles, video advertisement puzzles, etc.
I manage a forum at work and after a few years of no spam, suddenly someone found us and made hundreds of spam accounts and posts over one weekend. And Discourse doesn't have good bulk spam moderation in the UI, so it was a pain going through them afterward =/ I really wish we had a CAPTCHA!
