When questions are moderated, generally people use their best judgement to determine the merits of the question by itself. Does it meet our site's standards? Does the question make sense? Is it answerable? I don't want to say it's completely non-existant, but it's exceedingly rare that community moderation takes into account the country of origin for a question.
That is, community moderation is governed by humans who occasionally make mistakes or overlook certain things. One question might get the benefit of community moderation, while another slips through the cracks.
In the cases where a question slips through the cracks and you notice it, it's important to do something about it:
- Edit the question to bring it in line with our site's standardsstandards
- Comment on the question to provide feedback as to why the question doesn't fit
- Use voting to down-vote bad things, up-vote good things, and close off-topic things.
- If it's something that really needs attention right away, flag it for moderator review.
