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.
As I understand, he posted this stuff in marketplace and he isn't buying or selling something. So, first of all it's off-topic and at the same time zero value, trolling and spamming. I guess that when global moderator don't know that language, he just don't have other choice than using Google translate. But I have no idea why your reports is still unhandled.
As I said somewhere already, it would be perfect to have dedicated mod for every board, but as we know, things aren't always going perfectly as we would want.
