EDIT ^ at the above, I completely buy that it is Daisy. She messaged VW and added a line to her AW profile at my request. Unless her AW account was hacked (implausibly unlikely) then it's her. Admin has already manged to IP trace the culprit several times, so I can't imagine he's that hot at IT.
I read her reaction as believing what she's seen and heard herself rather than what other people are saying. On SAAFE the other girls are saying the guy appears normal at first, but has only recently gone off the rails. At worst, there is a bit of denial going on (not wanting to admit she didn't spot he was going to turn into a fruitloop, but sometimes you just don't see it coming). Although Daisy's initial reaction hasn't been terribly rational, having a pop at her won't help. She's more likely to listen and read up on the evidence with some more calm encouragement. I understand her posts look out of place, and I was suspicious myself at first. However I think it can be put in context of the fact she hasn't witnessed the meltdown(s) which some people have seen her in advance.
Well, what a mess this is.
Just goes to show that anyone can appear normal to begin with and flip - punter or wg. If there's a lesson or two here it's that discretion is priority one and you can never be too careful.
