Personally, I think it sounds really snotty. I mean, it is effective in real life when we want a person to stop commenting on our own personal situations, but on this board, where everyone knows that it is normally used when replying to a rude, overstepping person, I think it is beyond insulting.
If you post something on this board, it is fair game for people to comment on it. And if people are mistaken, it is up to the OP to correct that information.
