Moderation in local boards seem to be difficult question. There is few local boards which are more active than Greek and don't have their moderator. Croatia or India for example. And I don't know reason behind it. Maybe theymos see tha these boards don't have activity to have dedicated mod and global mod is enough. But IMO, it's better to have dedicated mod who knows that language, even if that board isn't very active. Especially if there is suitable person for that job. Maybe it's question of trust for theymos.
I'm genuinely curious to see how a person who doesn't speak Greek can verify that my report is accurate.
Google Translate is doing it's job quite well nowadays, it's not same terrible thing with nonsense translations as 10 years ago. But offcourse, it can't replace native speaker.
