Zack can't remove anyone ! Either you stop following the person or use Contact down below to contact Administration. I don't see anyone on your followers or following you. Anyone can comment on anything you answer or ask. Doesn't mean they are following you.
Anyone can comment on any answer if you are following them or not. If you are getting unwanted emails and notifications, go to your account settings, scroll down to notifications, click it and it will take you to email notifications, click the box and uncheck the notifications you don't want to recieve, then go down and click the blue box that says update. That will save your choices.
