She’s a friend of my mother-in-law whom has known my husband all his life. She’s very friendly but she’s very odd. She posts non-stop all day long often unsettling, inappropriate or spammy content (share this or else posts, people in hospital, people fighting, horrible news content, sick/dying people) and I find it extremely upsetting. She also often pretends to be hacked and makes multiple accounts for attention. (She’s in her 40s and has some mental health issues). She’s nice but I feel like I can’t remove her as she will message and spam add and talk to people about it and make me feel terrible for removing her. My husband said I shouldn’t because she’s mentally ill and it would be horrible to remove her. I don’t want this woman on my friends list and I have unfollowed her but I still see her posts and she still messages me spam content directly. What should I do?
