That is as far as the listing and Mindrift's country rules show: the listing has the last word, and rules change. Mindrift in Africa

Apply from where you live, as yourself. Using a VPN or someone else's identity to get around a country rule breaks these platforms' terms, and it is the quickest way to lose an account and any unpaid earnings.

About this listing

We last confirmed this opening on Nov 6, 2026, and it was posted on Nov 5, 2026. Rates and hours come from the listing unless the note beside the rate says otherwise. Where the listing names no countries, the Africa status is our reading of it and of what is known of Mindrift's country rules, set out on its profile, and never marks a role more open than they show. The listing itself has the final word.
