No, CAPTCHAs can and will be bypassed. But you can make it expensive for bot hosters using PoW CAPTCHAs instead of normal ones. It’s also better privacy-wise.

The whole point of captchas is to train bots. Did you think they were all road object and optical character recognition based because those are the categories humans really excel at?
