I think kyugima mean rude posts in general or things that doesn't really go against the rules. Mods and admins cannot really ban users just because they dislike some of the things they do or say unless it goes against the board rules.
Someone might for example ignore information posted, post sarcastic or pointless comments that's not really enough for anything at all but annoyance. I'm not sure how kyu and the other mods would be able to report tiny things to themselves xD
So if you spend a lot of time on the boards dealing with different kinds of users, chances are you will bump into someone that just do actions or post things that aren't really welcomed or liked due to lack of forum manners, but unless it's breaking rules such as swearing, spamming, racist etc. It will still be posted since everything can't be removed.
