Trouble is Justine, people go beyong just offering support and help. There were people ready to jump into their cars and go to help - where would they be going? That could have potentially dangerous consequences. Others have contacted her through CAT and will now, no doubt, be contacting her privately through email. So what if a meeting is set up, who are they meeting?
I agree that it's not nice to troll hunt, that suspicions should be raised with MNHQ and I think I said that on this very thread. But when you see people offering to drive there, sharing their email addresses, you become concerned for those people.
If you raise your concerns, at least you've given people a heads up and they might think twice before arranging a meeting. Whereas if no-one says anything, then it is generally presumed to be genuine and as we can see today, the thread is still there. So either it is genuine, or you are still investigating it.
Either way I think those people who are contacting her right now need to know.
