Hi. I don’t know if FB uses OSM or not.
In OSM, the place has been a “town” for ~12 years, and hasn’t changed recently.
https://www.openstreetmap.org/node/246671466/history
Given the population, town seems appropriate.
The corresponding boundary relation has been unchanged for 3 years.
Also please note, in OSM we don’t “tag for the renderer”, or more specifically, we don’t tag mistruths to get certain downstream effects.
