Since the traffic on Korean Beta SE is so small, the number of spam is not that big. However, we don't have a moderator appointed yet and I've just found that my spam flag aged away without being taken care of. We have to take care of them on our own until moderators are nominated. And we have to keep flagging them even if we have moderators.
When you see a post like Is there any equivalent proverb for "Slow and steady wins the race"?, please flag it as spam.
When you see a post like the below image, please flag it as "rude or abusive (offensive)".
When you flag a post as either of them, it will be automatically downvoted. You don't have to worry about losing one reputation point when flagging an answer.
- 3 flags on a question (spam or rude or abusive): question is banished from the front page and all question lists except search results.
- 6 flags (spam or rude or abusive): post is locked, deleted, and the author loses 100 reputation.
For more information, please read Meta SE question, What are the “spam” and “rude or abusive” (offensive) flags, and how do they work?
Please do not edit those posts:
Stack Exchange has an algorithm that automatically learns which posts are flagged as spam and tries to block those, and editing the spam can decrease the efficacy of the filter.
Edit: Expressing "from A to B" in a more concise way (another spam from the same user name who posted the spam above-linked)
I have just noticed that 3 flags on a question (spam or rude or abusive): question is banished from the front page is not happening. I guess it is because Korea SE is beta. I will update it when I find the reason.
