Well it wasn't stalking or anything serious like that...I was facebook friends with this girl who I didn't actually like, but we had a lot of friends in common and went to the same school, so why not. She was kind of a religious fanatic, which is fine, but not for facebook. I occasionally would post something religion-related from the news, and then she would take it as a personal insult and fill my personal messages box with hateful things. She'd just go off on how I was a bad person for believing religion was bad, and it just drove me crazy, especially since we never even talked in real life. Had to unfriend her!
