This?
Finding mods for foreign language boards presents unique challenges, so there's no real set way to go about that. Sometimes it's by polls, sometimes it's just because a certain person has expressed an interest in moderating the board (either by their actions, or by "applying"), etc. It tends to be a more community driven decision, because acting like you know someone because you used google translate on their posts is dumb (though foreign language mods do need to be able to communicate with us in english).
Yes, nice find.
The problem is, like Welsh said, most of the persons when they are in doubt about the post, they usually don't report it as if it is marked bad, their accuracy will decrease and it isn't really good IMHO.
I have the feeling we are derailing another topic in meta[1], but maybe here its more fitting because its closer to a mods work, reports and how they are handled.
I think its silly to not report something because you are not sure. Creating a report and watching your accuracy or the thread/post is a great way to figure out whether your opinion is somewhat in line with the mods. Even the most knowledgable mods make decisions that get contested and revised later[2]. I think this is a great misconception that wanders the board. The rules are considered guidelines for the mods and users alike and not strict laws. There is a reason the "unofficial" list of rules is not official. If the rules are set to strict people will start to find loopholes.
