Someone posts "i heard that he did a bad thing, can someone enlighten me?", and no one replied for 6 hours (= no one cares in such a big forum). So why reply at all? Are his nerves so bad that he feels the urge to reply with a wall of text to a single person, questioning his previous accomplishments by hearsay?
I do not appreciate folks who talk so much about their previous Job in front of customers and that grandmother comment was also not very kind. I rate it as completely unprofessional and not having themselves under control.
Blizzard is probably lucky to be rid of that guy.
