Ok. I had another look, LeMarchandsBox, to see if I could see what you are seeing.
Su someone was really nasty but that wasn't a name I recognised.
Then Usual was snide.
Then some people told them not to be so nasty. Among them
Chub
Northern
PerfumedLife
Bronze
Orenishii
Custardo
Alma
...
all jolly nice posters, but I can't say that I have noticed them being part of a crowd.
I think that people picked Usual up on her posts cause she is normally straight talking but kind. And this wasn't kind.
