Hello. Obviously just a welcome to the forum is falling short, but at the moment, it's all I can offer. I'm an older, single person and your situations are outside my scope. I'm sure someone here will be able to make useful suggestions.

This is intense and a terrible situation.
A bit confusing too. Who is threatening you? The biological father of the older son or the younger son?
I would go to the police, at least make a report. Possibly a restraining order. The more you document abusive behavior the more likely the police will help.
You could do a binding spell on the bio mom who is creating the false profiles. But how sad this boy is using his bio mother against you. Must be an adoptive parents nightmare.
Wishing you the best.

Oh! And welcome

Welcome to the forum Menina. So sorry to hear about your situation. That's horrible that your son is being so cruel. I pray that he finds peace in his heart.
