I Have Met Some Strange People In My Life

So I made some comments on a facebook post that featured "vegan sausage". It angered a particular woman I have never met. A month passed, I forgot about the comments but the woman didn't. She stalked into my facebook profile and put a laugh emoji on one of my career event posts. So I decided to give a taste of her own medicine. I got into her profile and did the same. I didn't expect much other than few rude messages from her but she went wild after that. At first she tried to video call me few times. When I ignored that, she sent a screenshot of my profile along with my location and threatened me. When I responded that with a laughing emoji, she sent a friend request and demanded to accept that. I said no. Then she blocked me. Not long after that, another woman claiming to be the crazy woman's sister, messaged me to stop "stalking" latter woman. I sent all the screenshot of her sister's conversation and her friend request to her and asked her who's the real stalker. And that woman blocked me and I never heard from any of them ever again.
