I have read that LinkedIn will actively solicit your information to people that are near you once they find out where you are, and they will actively take steps to continue knowing who you are, even when you actively took steps to prevent them from finding out (like not logging in, and not accepting their cookies.)

Also they have been accused of dark patterns before, like that would result in people getting e-mail that purports to be from you, when you think you already unchecked the box and asked not to share your contact list.
