Why the word japan was censored to ###an?
Dont censor jap if it was combined with an.

Dont all players live in USA
Maybe only censor it if the game detects that the player from USA?

because everyone knows americans are the only one's capable of racism towards the japanese right?

in any case it seems rather stupid to censor it in the first place. if someone's gonna be racist to japanese people a swear filter is unlikely to stop them and you should symply make it easy for players to report their message
