Aibu to stop contact with my children?

[NewDayFreshStart]

I just need some validation I guess to make sure I have made the correct decision as I have never stopped anyone from having contact with my children before. NC for this.

My sons auntie has had it in for me for a long time, we stopped speaking to her eariler this year & blocked her on everything when she accused us of some very serious & untrue accusations. To outing to list here but it was bad.
She somehow made a new sm account and managed to message me, firing abuse at me constantly saying I neglect my children because very, very rarely I will have a odd drink and that in her eyes makes me unable to take my children to hospital if needs be. I would never drink if my children were unwell, and out of 12 months Ive drank twice and never to the point I dont know what I am doing.
she ramped her trolling changing her profile photo & cover photo taking the mick out of me. She accused me of stopping her having a relationship with dh even though it was his choice as he was sick of her behaviour as over the years shes caused many, many pointless arguments.
She then violently threatened to come to my home with the children inside.
So I told her to never contact us or my children again as I do not want her influence around them
piror to that I was happy with her contacting them but she went to far this time.
Was I wrong? i feel like I need to protect my children from her. I know this may seem like a stupid aibu but I just need someone to tell me its okay I guess.

If you need to vent about this woman that's perfectly understandable as she sounds absolutely awful.

But it's a bit silly to ask if you're being unreasonable to stop her having contact with your children.

I mean who in their right minds is going to say 'Oh yes, you're terribly unreasonable'?

Cut her out of your lives, stop accepting strange friend requests and lock down all your SM.

Nope. I would have done the same. She sounds utterly toxic and maybe mentally unwell. Your children’s well-being is paramount.

I just wasnt sure as part of me feels it should be my childrens decision to stop contact with her; not mine but they are really to young & its not something I can speak openly to them about.

Of course you should protect your children. I hope your DH is in complete agreement. If she threatens you or harasses you, you should report to the police.

Yes DH is in complete agreement and keeps apologising to me even though its not his fault. She has slandered my name publicly with false accusations all over her facebook account too.
I am highly considering reporting this to the police.
I have just deleted all my social media accounts including whatsapp & now on the phone to my phone provider to change my number.
What worries me most is that she has my address.
She doesnt live locally, and doesnt know anyone around where I live but I worry someone may fall on her facebook profile and see all this.
Shes accused me of being a child neglecter, child abuser, drug addict, acoholic, all kinds of bloody things that simply are not true.
My family are aware of her previous behaviour & obviously know me well enough to know none of it is true, but I worry about local friends/accquitances seeing it!
