Not sure about Pink Essense, but the forums that really annoy me ar those where anything that doesn't strike a chord with some moderator, or which is deemed to be in the wrong section, is deleted.
A few years ago, on the old MSN forums, I was in a women's forum where I generally got on quite well.
Then someone starts a thread claiming that all the differences between men and women are social. I disagreed and was deleted. I just stopped posting there, after that.
But, at least, on Facebook, you can tell her where to go.
