It's not that we aren't accustomed to hearing strong words, it's part of our jobs. We want civility because it's easier to gather feedback when a post is succinct and not full of asterisks where a swear filter takes over, or when we simply get messages that is a string of insults and no feedback. We're also looking out for the new members to the forum, and minors, and other people who want the forum to be a fun place to meet fellow players of the game.
I can't stress enough to you that the Community staff is not out to "screw" you over. It's our job to advocate for you, and we enjoy doing it. When we enforce forum rules we're just doing our job along with reporting feedback to the teams. We aren't programmers or developers so we can't fix anything ourselves - that's not meant as an excuse, it's merely an explanation as to why we might not have technical answers for you. When we receive information, we certainly report it back to you.
And to answer your question: "Did you want to speak kindly to blizzard when Diablo wasn't functioning as it should?"
I've been a Community Manager for years, so I see things from a different perspective. Yes, I wanted to speak kindly on their forums and social media because I knew the staff there were advocating for me and providing information as they received it. I knew that I'd be putting them in a situation where they'd have to delete my posts or issue an infraction when they could be communicating with the team. I was really angry, too. I spent some good money on that game for it not to be playable, but the people working on the forums/social media weren't out to screw me over, they were trying to help me. In the frenzy of complaints they were getting, they were doing their best to help.
I like to use this analogy - It's kind of like yelling at a cashier when prices go up.
Anyway, I didn't do this to argue with you all, I just wanted to shed some light on this and let you know that I've been an angry video game consumer before and I understand the frustration you all are going through because I've been there.
I hope you all have a nice evening.
