I've just had a look at her Facebook again today.
Her latest post (from a few days ago, suggesting she has another Facebook ban) now has a comment on it.
There are never any comments, because leaving a comment isn't an option; comments are disabled. You can like and share, but not comment.
The person who has commented has her on their friends list.
This suggests to me that comments are only disabled for people not on her friends list. Friends can comment.
Yet not one single person has, until now.
I always suspected she was socially isolated, and all talk of her "professional" friends and lawyer boyfriend were fabricated.
But this suggests it goes deeper than that.
It looks like she is completely isolated, to an extreme degree. Absolutely no interaction with anyone.
I also got the impression from the Piers Morgan interview that she has no contact with her mum but didn't want to come right out and say that.
The fact that nobody on her Facebook interacts with her is very sad, but it does speak to what a dangerous person she is and how reluctant people are to engage with her.
It's not hard to see why she latches onto people who offer her the smallest shred of interaction.
