Question 1

How do I integrate MotionCAPTCHA with my existing PHP form?

Accepted Answer

You'll need to manually disable the form action, add a hidden input with the action value, and initialize the plugin with jQuery—but note, server-side validation isn't implemented yet, so it's client-side only. The README provides a step-by-step guide, but it's complex and not production-safe.

Question 2

Is MotionCAPTCHA better than Google reCAPTCHA for user experience?

Accepted Answer

For users who prefer drawing over text entry, it can be more engaging, but reCAPTCHA is more mature, accessible, and widely supported, whereas MotionCAPTCHA is experimental and lacks key features like server-side checks.

Question 3

Does MotionCAPTCHA work on all mobile devices?

Accepted Answer

Yes, v0.2 added support for Android and iOS with touch drawing, but it still requires JavaScript and Canvas, so it won't work on very old mobile browsers or if those features are disabled.

Question 4

Can I create custom shapes for MotionCAPTCHA?

Accepted Answer

You can configure from a predefined set of 14 shapes via the options, but adding entirely new shapes likely requires modifying the underlying gesture recognition algorithms, which isn't straightforward.

Question 5

Is MotionCAPTCHA secure against bots?

Accepted Answer

In its current state, no—it relies on client-side validation which can be bypassed; the roadmap includes server-side checks for security, but they're not yet implemented, making it vulnerable.

Question 6

What happens if a user has JavaScript turned off?

Accepted Answer

The form remains disabled and unusable, as the plugin requires JavaScript to enable submission, breaking accessibility and degrading poorly compared to progressive enhancement plans.
