Do you mean that they should make only one community for these type of posts?
Several communities are global. In my case, I published in Terracore community, but if I had written the post in Spanish, I would have posted on NFT Game Latino, a general community for NFT gaming posts, but in Spanish.
I don't know. I think we are too fractured. Perhaps I view the whole issue wrong.
I think that it is ok to have niches.
