Data and lists that you've marked as private will not be displayed. While logged into your IMDb account, you'll still be able to view this information on your activity page. To quickly view what's been marked as private, we recommend viewing your Activity page while logged out of IMDb.
Badges you've earned by rating or contributing to IMDb will show on your IMDb activity page. There isn't a way to hide these from public view at this time.
All IMDb accounts will automatically have an activity page. There isn't a way to remove your activity page, except to delete your entire IMDb account - rather than deleting your account, we recommend marking your lists and ratings as private.
