Hi all-- I am the creator of FunCaptcha. I really appreciate the discussion of how well it is working... especially that quote above that shows how bots responded when you switched. We try to add to our "case studies" of great user stories like this. FaucetWorld, please contact us or reply here to let me know if it's OK to use your quote and your chart to show people how well FunCaptcha works.
Also, if you have any problems, I will try to answer them here. But your best first stop is our support page (click the ? mark in the footer of FC). There are good FAQs there and a way to submit a support request.
If you like videos, search for us on YouTube. I'd link them here but don't want an algorithm to falsely accuse me of being a spammer.

Hopefully subscribing to posts here will work, and I will try to answer back soon if anything comes up. Meanwhile, enjoy FunCaptcha. Keep in mind we offer a few different security levels that trade off bot-proof vs usability, so if you do suspect bots getting through, contact us so we can work together on your settings.
When are you going to think about adding new puzzles? The one with the woman and the man is really creepy.
