Anyone else's Nparents actually stalk and befriend your new friends and partners?

I mean actual stalking. Anytime I get a new friend or partner, my mom will look them up on social media, run some degree of background check, gain their contact information, and then she will contact them. She makes it clear from the start she is my mom, but she will then spend time befriending them and gaining their trust.

They then become a weapon for her. She will manipulate them into saying or doing something that will hurt me (that they don't realize will hurt me), she will convince them not to trust me when I say she is hurting me, and she will lie and claim that they have said/done things against me. She also tries to get them to like her more than me, not necessarily to steal them as a friend. She just wants to be the center of attention, I guess.

I have stopped giving my mom my friend's/partner's names, but she still tries to find them out. She quite literally stalks anyone who has a similar name.
