My sister is stalking me online now.. !!!

She is so annoying with the way she keeps sharing with me family news that I never asked for even though I showed no interest before... I just want to live peacefully away from all that and she is actively trying to include me in, something she NEVER bothered to do when my mother was alive and I was living with the family. Now when i got away, she is doing it.. what is the explanation of that??? What are the motives, control or love? Because i don't seem to understand why now, why not before during my mother's life? Why when i got independent and started living alone whether back where i lived or now in another country?

All I see is that before, she knew I was going nowhere so it is okay no need to give any efforts to reconnect with me.. now she sees risk, so let's give some efforts. I really see no compassion..
