The filter allows parents to prevent their children from seeing it when people fail to follow the rules.
You agreed that in game, and on the forums, you will not use profanity, hate speech, slurs, etc.
Just like having a bullet proof vest does not mean you can shoot at a person.
Mature Language Filter (aka The Profanity Filter)
This can be activated within your Interface Options: Main menu (ESC key by default) Click Interface > Social and check - Mature Language Filter.
Once enabled, all inappropriate words in our profanity database will be filtered and masked to appear as jumbled characters, such as ‘*##@&’.
Note: The filter does not excuse the language used. The filter serves as a temporary shield, to help parents of minors and others who do not wish to see it, to block it. Our policies prohibit the use of both clear and masked inappropriate language.
