Very good point!
Accessibility is a critical to mCaptcha. In fact, Codeberg is trying out mCaptcha purely because of its more accessible[0]. That said, it is possible to choose a difficulty factor very high to deny access to folks with older, slower devices. A survey to benchmark mCaptcha performance on devices in the wild is WIP[1]. I hope it will provide insights to help webmasters integrating mCaptcha to select difficulty factors that work for their visitors.
