How do I report my sister and get her off of Facebook without her seeing it?

[Kiddish]

My half sister is being really mean to my mom, calling her the "w" word and saying that she's a money hungry "b" word when she didn't do a thing to her. I want my sister taken off of facebook, because it really is bothering me.

i don't think it shows that you reported her.
i really don't think it does.
so, go ahead and do it if you want to.
have a good day and good luck.
