Thomas Marzahl suggests:

As an editor at Agence France-Presse, I frequently run into the word
“dusty“, usually used to describe a town or village where not much is going
on and is rather run-down. Inevitably it’s a place in the Third World or
developing world… I don’t think there’d be a lot of people who would
describe a small Bavarian village or an English hamlet as dusty. So it’s the
Tubmanburgs in Liberia, or Bunias in DRCongo that get labeled as such…
carrying with it a whiff of condescension.

Banned for life? I’m not sure. But dusty should be used with extreme care.
