No, your statement is an opinion.
In your opinion what was stated is something a shill, rep or employee would say.
Yes it has, multiple times. In fact in 2020 Blizzard handed out a large manual ban wave for people who were using profanity and being toxic in voice and text chat in Overwatch.
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.
