Just leave me alone ffs

I stopped using Facebook because my biological mom won't leave me alone. she has both of my bio sisters trying to talk to me for her or keep an eye on me, and each time I think she's gone she pops right back up. this has been going on since 2012. I don't want to talk to her, I don't want to meet her, I just wish she'd get the hint and go away. she keeps making accounts and finding different ways to get in contact.
