I personally think there should be a slight filtering then, if not every swear word can be filtered, but some of them. Like the f word or the most known 4letter words.
every sane developer wants to hold their game clean, and they do not want to see everyone cursing all they want.
yes, we all know there are immature ppl everywhere... but if we do not take steps, the problem can be really bad. Like... everyone blocks everyone... they cant RP together... there go the players.
I have been in a few games where you had a free chat, and no, they didnt filter it.. and yes, once they had enough and filtered the chat.
Its in the rules as well...
"3. Any sexually, threatening, hurtful, harmful, abusive, hateful, and ethnically offensive language is prohibited."
If they cant keep ppl to the rules.. then dont make rules....
simple as that.
