I've got an Instagram account I've set up for a sideline business which I don't necessarily want friends and colleagues to follow. Today I've had new follows from two people in my contacts list. My settings aren't syncing my contacts and I'm at a loss to know how this happened. And my son said today he had a notification from Instagram that his contact 'mum' was on Instagram and inviting him to connect. This is what must have happened with my new followers but I don't want this to happen. Any ideas what I can do?!
