Manic friend oversharing on social media

A close friend of mine is currently in a manic episode. She has a fairly large following online and has developed an addiction to social media. She is posting stories and videos sharing personal information regarding her ex-husband, which is very likely furthering the possibility of losing custody of her children. Thousands of people are witnessing her mania, and I can only assume this will be used against her in court. I just want to snatch that phone out of her hand or yell at her to STOP but I know I can’t do either…. Her wonderful family is using every tool at their disposal, but she is an adult and they remain respectful of her autonomy and healing journey. Is there any way to help her here?? Is there anything to say to try to make her understand she’s hurting her case and she should get off of social? Or do I just let it be what it is and stay supportive of whatever stage she happens to be in?
