Did you report it?
I totally can see how your post came off as hateful, even if that wasn’t your intention. I interpreted the note to say “you’re getting a bit too close to the line.” You know, that you’re not violating any rules yet, but that it came off as getting a bit heated. It’s probably not a good idea to refer to yourself as “piling on,” for example.
But, yes, the post you mention is much worse. It reads like a rant to me. If you are to be moderated, then I agree she should be, too. Heck, given a previous incident in ATMB, I could see justifying a Warning.
