Mods don't have to speak your language in order to moderate your board and remove spam (I guess they use Google translate).
I believe relying on a machine translator isn't better practice than having a native speaker of that language as moderator.
For example, Croatian local board doesn't have own moderators for the last few years ever since Lauda was removed so now we depend on the global mod sorting our reports.
I don't have a firsthand experience with the Croatian board, maybe there is a global moderator who knows Croatian, or maybe it's sufficient for a global moderator to translate using a machine translator for the Croatian board. I'm not 100% sure, I just make my observations, one of which is: if you've found a somewhat established, trustworthy, active forum user who's been accurate on reporting posts elsewhere and who natively speaks the local board's language, then it's more appropriate to have him moderate the board than a global moderator who's more prone to failure.
There must be some moderator who is responsible for your local board, maybe it's Cyrus or someone else.
As far as I know, the only Greek moderator is mitzie.
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.
Maybe theymos or a global moderator can enlighten us.
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.
Try translating the posts from the thread I linked, and tell me if you can verify that it's off-topic, zero value, trolling and spamming. I'll wait.
maybe if blackhat can moderate without a slant leaning of favouring certain topics over others or users over others due to some social drama he has occupied.
Rules above personal interests. That is taken for granted.
