I thought when I read the title of this thread that the conversation was going to discuss ideas, promote criteria and somehow increase traffic to local languages, but OP is worried that admin wasted his time, seriously, man, in reality this forum has more sections and diversity of topics that make it accessible to a large community,
I think that in principle that is the idea, not to let users escape regardless of where they come from.
For example, you do not mention the Spanish board, but that is not indicative that the section is better than those mentioned. It is just that by not being in your data table, it only indicates that there is activity, but how good is that activity.
That said, when looking at those boards that you mention, I am not surprised by their low traffic in some of them, because let's say that population-wise it is a low density of users.
But in our case, there are more than 500 million Spanish speakers, it is not justified that the monthly limit is sometimes 5 users, and I think I am exaggerating.
Finally, let's talk about what can be done, things like improving SEO, encouraging participation, etc.
