Technically, Jonumbers' post was not personal, though anyone could be forgiven for thinking it was. I suspect that that's what made the difference if Bluebell said something personal to Jonumbers in response. such a response would come naturally after such a remark in such a place, after all.
So what you need to do, Bluebell, is find a way of saying what you said without it being obviously directed at a particular person.
Jonumbers' comment could, at a stretch, have been referring back to my comment and Movedalot's and not to Gigi's at all. I think that's how she "got away with it". It is rude, you see, but it's not personal. Or, at least, it can get away with being interpreted as not personal.
Best of luck refining your skills, bluebell
