My teacher stalks me and my classmates in facebook

A lot of people probably do that and also my teachers but the thing is she said it in class (ex. A specific event) "blah blah facebook" and she said she's a proud stalker lol and she said she's not embarassed to say it. Then the second time I had that class on the same day she said something simmilar like"Do you know that feeling that you're friends with your relatives in facebook and when you're in the family photo then comments are like wow brother is so grown up now" something like that and the third time around which was just a few days ago she said it's not stalking it's researching and I'm just disguisted okay knowing that a role model and an adult figure creeping up to every shit you do.. Goodluck using your research in our topics. Nice to know what you do in your free time.. Stalking people and you're not contented with your life
