Blizzard has always had a strong stance on what is appropiate and what isn’t appropiate, especially along the lines of chat. Things like profanity has never been allowed within the game. Even with the language filter, it doesn’t change the rule around. If anyone uses profanity, they are then of course subject to action. Now, Blizzard is usually pretty lenient when it comes to taking action, as they give people a chance to change, but if people refuses to take those chances to change their behaviour within the game, then that is when the punishment gets a lot more harsher towards the player, eventually leading to the closing of the game license or the closure of the entire BNet account.
B. Rules Related to “Chat” and Interaction With Other Users.
Communicating with other Users and Blizzard Entertainment representatives is an integral part of World of Warcraft and is referred to in this document as “Chat.” Your Chats may be subject to review, modification, and deletion without notice by Blizzard Entertainment. Additionally, you hereby acknowledge that Blizzard Entertainment is under no obligation to monitor Chat and you engage in Chat at your own risk. When engaging in Chat in World of Warcraft, or otherwise utilizing World of Warcraft, you may not:
(i) Transmit or post sexually explicit images or other content or language which in the sole discretion of Blizzard Entertainment is deemed to be offensive; nor shall you transmit any unlawful, harmful, threatening, abusive, harassing, defamatory, vulgar, obscene, hateful, or racially, ethnically or otherwise objectionable content or language, nor may you use a misspelling or an alternative spelling to circumvent the content and language restrictions listed above;
(ii) Carry out any action with a disruptive effect, such as cause the Chat screen to “scroll” faster than other users are able to type to it, including setting up macros with large amounts of text that, when used, can have a disruptive effect on the normal flow of Chat;
(iii) Disrupt the normal flow of dialogue in Chat or otherwise act in a manner that negatively affects other users, individuals or entities, including, but not limited to, posting “Spam” messages on World of Warcraft (“Spam” messages as used in this document include, but are not limited to, any effort to use a computer or other electronic device to post an unauthorized and/or unsolicited advertisement to World of Warcraft);

(viii) Cheat during game play, including but not limited to modification of the game program files.

Original User Manual also backs up the statement.
This has nothing to do with people being sensitive or being in kindergarten. Let me put it this way, and this is only on the basis of my own opinion, but why do you think the toxicity within the game isn’t as bad as some other games?
If Blizzard did allow for people to get extremely toxic, then things could go way down hill for World of Warcraft.
I mean, it is here in Australia

But Australia is not the only country that plays WoW.
