No it doesn’t.
Do you see football players going on tirades of profanity when their team doesn’t win a game? Do you see professional swimmers or track sprinters go off on their coaches or throw a fit towards the other people in the race when they come second, third or don’t finish? Is the Olympics filled with immature people acting like unruly children when they don’t take home a gold medal?
No.
These are some of the most competitive sports in the world, no athlete goes on tirades of profanity or curses out anyone. Hell you don’t even see that happen in professional eSports. When the Overwatch League was a thing, you didn’t see professional teams throwing profanity at their own team or the enemy team because they were losing.
Don’t try to claim that ‘competitiveness breeds profanity and permits it’ because it doesn’t. It is unnecessary.
Are you seriously comparing slavery to me stating a fact that profanity is not allowed in Overwatch and never has been? Really?
People have been getting banned for years. In 2020 there was a post from Blizzard developers themselves outright saying that they were going to be conducting a ban wave to remove toxic players from the game.
UPDATE (Oct 12):
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.
And you can find posts on this forum from 2018 and earlier from players complaining about getting banned for language despite the fact that the profanity filter exists.
No it isn’t. Maybe to some extremely conservative religious folks it is, but to the vast majority of people in the world it is not, and that’s why it isn’t blocked by the profanity filter.
