I hope you find help here. I am also interested to know how a non techie Mom fou d HN in the first place :-)
My Facebook account was protected with 2FA and wasn’t compromised — no shady posts etc. In fact I don’t use Facebook much at all, only logging in occasionally because a local sports group uses it to coordinate.
It was, however, flagged and access denied. The way out was to provide government-issued ID to Facebook to get it unlocked. I suspect it was reported as “not a real person” for some reason. I did spend some time wondering if it was even worthwhile keeping my Facebook account — even after they unlocked the account I’m not sure.
Anyway - it’s just a cautionary tale, don’t get too attached to anything on a site you don’t control.
I bet is just google doing google things :)
I'm her techie father.
She is distraught and beside herself about this and I was hopeful that someone with influence might see it and help her as I have so often seen people regaining various accounts after appealing to the hive mind of HN :-)
