To want to block DD's GM on social media

[Winosaurus]

Long story short, I am from and love in the U.K but whilst on a gap year I had a brief relationship with an Australian man which resulted in a child - my DD.
He "supported" me through my pregnancy but went NC when I was 7 months pregnant and we didn't hear from him again until just after she was born when he basically said his new partner didn't like the fact he had a child with someone else and he wouldn't be in contact again.
True to his word he didn't - other than to tell me he had a daughter with this woman 2 years later.
His mother decided for a while to keep contact via Facebook and emails until my DD was around 18 months old but just like her son she suddenly disappeared off the radar.
Ignored my messages and stopped the interaction between us, even deleting me off Facebook which was our main form of contact due to the vast geographical distance between us.
Now my DD is 7.5 years old and this morning I have woken to a Facebook notification that GM has liked one of my public posts - a rant about some local scammers, not even related to my DD.
But this means she must be snooping on my profile trying to glean information about my DD... but why? Why doesn't she just ask me herself?
I have not prevented contact and even after the horrendous way both my DD and I have been shunned by the family I have always made it clear the door was open for contact... for any of them, not just her Dad.
Anyway this sneaky profile stalking has really upset me and made me angry if I'm honest, I may block her or make all the pictures of my DD private - there's not many anyway except a couple of family shots with my DP and my children (I have a 3 year old son too).
I'm so hurt and feel she's lost the right to view this pictures. She chose not to have any contact and she could easily call, email, write a letter (she has our address)?!

I would block her and anyone else related to her that you know. Whether she'd been snooping or not, I wouldn't like the thought that she could if she wanted to when she was otherwise NC.

I would block her without a second thought.

I agree with this:

If the new woman didn't like your dd in her partner's life, this may have eventually extended to the GM. Perhaps she was made to make a choice between a GD over the road or one half way around the world. I'm not saying this is true, just a possibility. I think you should remain the good guy.

You have been amazing in taking the high road for so many years - not sure I'd have managed that. Given you have remained the 'good guy' for so long don't blow it now. Whatever the reason GM is thinking of you and your DD - yes of course she should just contact you but you don't know what's gone on between her and her son.

I think you have all misunderstood or not read what I've previously said

Sorry OP! Completely missed that bit, just ignore me

You are already the good guy OP. Don't let this incident upset you. She's the one losing out here, I'm sure your DC is fab.

I ageee that she probably "liked" the post in error but there is also the possibility that she is (clumsily) reaching out.

Hardly surprising or weird that she might want to have a look on Facebook for information about an stabbed grandchild. She would not have contacted you because she knew she was in the wrong cutting contact with you years ago. People look on FB all the time for info about people they don't want to contact directly, be they exes, old schoolmates, former colleagues etc etc.

Obviously the "like" was a mistake. Could you see your way to rising above your initial annoyance and just sending a quick email saying you saw she'd been looking at your FB page and giving her a quick update on DD and sending a pic? Would that not be a nice way to keep these avenues open for your DD in the future. For all you know she might be terminally ill or something.

Aargh autocorrect! No idea where "stabbed" came from. I meant "estranged".

Block the bitch. Why would you even want your dd to be in contact with people who have rejected her?

Jessie she clearly doesn't want to be contacted though as she's set her profile settings so I can't add her or send her any messages - the option just isn't there. Also she's blocked our email address as they began to bounce back.
I did send updates for 4 years to both her and my DD's dad even though I would receive no reply but it became to painful and upsetting for me so in the end I had to draw a line under it.
I haven't blocked her but I've put a public status saying I know she's looked at my profile and if she wants to contact she can, there is nothing to stop her

That's nice you did that.
