Girl, I understand you wanting to have your sis focus more on her studies. I as a little sister would very much like to have my big sister stop going out so much and instead focus since she soon finishes school. But that does NOT mean that you're allowed to just ban your sis from something, imagine her doing that to something you love and that keeps you going. I myself as part of a rather large online friendship group can say that being without it can be very VERY problematic, it's not being obsessed with it but the worrying if your friends are okay. It's same as when you can't talk to your irl friends, you never know if something might've happened.
If you want your sis to be happy and able to focus then do your best to have her be treated fair and just like you're treated, otherwise she wouldn't be able to focus anyway even with her not being online as much
But stay safe and take care of yourself and her.
