You need to compare that to the average cost per click for an IG ad and how much one would spend to keep it all going for a month straight.
Tatelicious' one is way cheaper but the problem might be her audience.
Most people who have time for both Tatelicious Karigambe-Sandberg and Mvenge Mvenge Ezomgido Group are females and fewer males.
So it wouldn't be much of a big deal unless the client was looking for an exclusively male audience.
Or if the client was more careful about their "brand values" being associated with Zim celebrity drama.
