Yeah for normal and safe stuff like favorite book series it's easy. For mental health where you need to moderate suicide topics and disinformation that's whole another challange. Those spaces should be made top down not bottom up. The moderator should really be an experts on that not some random basement dwellers. (My view is enteirely based on r/HealthyGamerGG@reddit.com)
Usually it's easy, but when I role played that I don't know one language and I know the other. It was super hard.
I was making a game for kids where they need to use some english (second language) to progress the game, and I slipped and reacted to the native language.
Unironically it will work as @Thorry84@feddit.nl and a bunch just like him has put in the work to Just WorkTM
