Whenever someone reports or when we stumble upon, we will act on it.
However I personally doesn't think it's worth it to compile a list because to me, it's just pure common sense. You don't make fun unto others when you do not expect to be treated the same.
Those who are familiar with /k/ will know that we even suspended someone for using "ching chong"/"nigger" as well as other slangs meant for racial insults. So when we suspended Indonesians from using the word "Malon"/"MalaySial"/"Malonsing" etc... we also do the same on Malaysian hurling the same insults towards ourselves as well as towards our Indonesian neighbour.
