World of Warcraft now automatically blocks messages containing “reserved words” such as slurs and other banned or derogatory language. WoW-focused outlet Wowhead discovered the change on live servers recently and published a post about the change.
As with most online games, WoW has used a text filter to automatically censor and filter certain words for years now. However, this new system–which only applies to one particular racial slur right now–appears to indicate that Blizzard is planning to punish derogatory language more harshly in the future. The new system blocks the message from being sent on live servers entirely.
Given this only applies to one word, it’s likely this feature is experimental, but could include more words soon.
