I've been reading alot of complaints by posters here in Korean chat about the mods showing favoritism towards Chinese-biased posts or Chinese trolls over trolling posts which defend or favor Korea, Vietnam, Japan, or other categories. I didn't think it was really a valid claim until I did the following test.
Under a different account, I made several intentional nationality-trolling posts. I used the words "g.ook", "j.ap", "n!p", "flip", "viet", etc. in several posts last week and these posts are still here.
However, whenever I made a post or reply with the word "c.hink" or anything remotely close to sounding critical of Chinese, my post was deleted almost immediately after refreshing my web browser and posting. I would say the longest that any of these posts lasted was probably under 30 seconds.
Go figure.
