can i report someone without knowing her exact address or her children’s names?

i saw a girl posting photos of her young child on facebook in bikinis/half naked with seriously suggestive lyrics (she posted pics of her to the song WAP), her baby’s father also sells drugs out of their house and posts about it online/posts pics of money and illegally obtained cash/weapons. her mom is constantly online cyber bullying and harassing other women that i am mutuals with. it seems like a very toxic environment and although i have never had issues with this woman or her baby’s father i am concerned for their children.

i know both the parents full legal names and the township they live in, and their birthdays are public info on their facebook profiles. and i can link to the social media posts. is there any way i can still report and potentially help these children without knowing the address? or would it be a waste of time unless i know where she lived exactly?
