How can somone see me online on facebook messenger if we aren't Facebook friends?
I was wondering, how can someone see me online on Facebook Messenger if we aren't Facebook friends?
If someone is able to see you online on Facebook Messenger, it usually means that they have your phone number or are in a conversation with someone that you are also talking to. It's also possible that your Facebook profile is public and they are able to see your activity.
