Mayotte kan ju inte vara så oexploaterat. De har t ex en site med turistinfo:

Enligt Lonely Planet:
Yes, it has fantastic white sand, turquoise sea beaches and excellent diving, snorkelling and sailing, but otherwise Mayotte (Mahoré

is overpriced and some say over-Frenchified. A collectivité territoriale (overseas territory) of France, Mayotte differs from the other Comorian islands politically in that its people are French citizens governed by French law. As a result, French citizens donÂ’t need visas to holiday here, and the island is crammed with holidaymakers on packages from all over France. It also has a large expat and diplomatic community in its capital city.
