And here’s another post, this one by Blizzard themselves, in 2020
Remember that the existence of profanity filters does not make it acceptable for players to use offensive, hateful, or language that violates our In-Game Code of Conduct —and as always, we encourage you to report instances of such behavior if you encounter them. Using language report by the community and deemed offensive by Blizzard will result in severe account restrictions.
In addition to the improved profanity filter and updated penalties for inappropriate language, we’ve also performed a manual action wave against some of the worst offenders of toxic language in Overwatch. This action will take effect with updates to profanity filter and penalties in the next live game patch.
