Thank you @ashley-ghastley! If others can enjoy these translations/contextualizations, I'm proud to be doing them. It's also great that you're using your Steemit account to log your journey learning Korean.
I'm not 100% sure on what specific posts you're referring to, as I've seen many instances where people do upvote comments. Still overall, most KR members try to be more precise with their votes/downvotes. Because the community more tight-knit with more regular interactions with their audiences, upvoting comments can also be seen as giving too much preference and usually reserved for supporting substantial whole posts.
Hope that answers your question a bit.
