Finding a compromise between usability/accessibility and security is difficult. We want to make it easy for humans to minimize errors whilst also making it harder for bots, so we're happy that you think the challenges look easy. One of the differentiators in ProtonCAPTCHA is that we've built this system with the expectation that someone will break it, either through automated mechanisms, or via third party solvers - however, there are defenses against these attacks in place which we will not divulge for obvious reasons.
