I get people sending me messages with just a greeting or just saying that they have a question, but without an actual question. They try to be polite, but in reality they are wasting my time and their time as well. I see the same thing in this chat sometimes, where people would post something like a greeting with no further value added to the conversation. So in order for us to stop this and understand why, I suggest everyone to read this short URL from Microsoft that goes to a GitHub page that clearly explains why you shouldn't do that:
