Feels like everyone trying to learn/improve on what caused them to get a ban/penalty gets put down even by heralds/mods.
For starters, if you want to discuss the behavior of the Moderation team, you'll probably want to go to Discuss the Boards or take it up with someone in the NA Boards Discord.
Beyond that, I'm seriously doubtful that the Moderators/Heralds have spoken down to anyone recently, much less throughout their time in the position. They hold themselves to a pretty high standard of respectfulness and impartiality, so unless you've got evidence, I'm gonna have a hard time trusting what's already put forward as a subjective feeling.
And, like KFCeytron said (though not precisely), more often than not, the people who come here asking about their punishments seldom actually want to or try to learn or understand; I can see how the responses to those players can be seen as putting them down, since, naturally, when folks are uncooperative, it's going to color the responses they get from people who initially try to help, but at the end of the day, it's a two-way street.
If one party isn't coming at the other even, the discussion isn't going to go anywhere, no matter how civil and respectful the other party tries to be.
So if people really want to learn and improve, they wouldn't shut us out when we explain where they stepped over the line, and they wouldn't adamantly insist that they did no wrong, or that their behavior was justified by someone else's misbehavior - etc.
Most people are trying to learn, or at least get a secondary opinion about what they did.
Again; more often than not, we wind up seeing people shut out opinions that disagree with them. There are certainly a fair handful of people who do try to understand and learn, but the greater portion are looking for validation or an echo chamber.
And you can explain the same stuff over and over 'til the cows come home, but if the person you're trying to explain it to refuses to hear it, then they're not gonna learn.
I actually feel like some of the comments on this forum would be getting you a chat penalty in game lol.
Some, I've seen, yes. And typically, those comments also earn some form of punishment on the Forums when reported, too. Mostly comment/post pruning/removal, but sometimes warnings and temporary suspensions are used when someone is proven to be belligerent.
But am I the only one who's noticed this?
"Noticed" is probably the wrong term to use here; at least, it's inconsistent with your opening by saying that what you perceive is "feeling". So, for the sake of semantics, I'm going to take this question as "has anyone else felt this way" instead of "has anyone else noticed this".
And the answer is that there are doubtless some out there who feel the same way as you. I myself ain't one of them, being frank. I've hung around PB for a while, so I'm pretty well familiar with the way discussions go. While I can say that there are some (myself included) who could certainly do better to keep composed when people start throwing up walls, I wouldn't say that people frequently talk down to others.
Not to mention mysterious amounts of upvotes or downvotes that are multiple times the actual comments.
Define "mysterious". I personally start considering it sketchy when a comment/post jumps to 30-40 votes in under an hour.
