Fully remote. The listing does not name eligible countries, and Mindrift sets eligibility posting by posting.

Africa unclear

The listing does not say. What is known of Mindrift's country rules is on its profile; where that does not settle it either, you may only find out by applying. 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 Oct 29, 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.
