So i was in a huge group chat, and someone who i didnt know added a contact, lets call her Katie, who was already one of MY contacts. That means i already knew Katie. There is a Katie in my grade, so I assumed it was her. She was getting really annoyed with the group chat, saying it was stupid. So i messaged her to leave if she wanted to and we werent making her stay, then she called me creepy for being talked to by a "stranger" and i got rlly confused. i asked her if her last name was the last name of the Katie in my grade, and she said no. She reported me. I removed her contact, and saw her email address is the same as the name of an fa user. im worried that may be her.
