Paul Ducklin, Sophos head of technology in Asia Pacific, suggested that LinkedIn is making the same mistake as Facebook with its much-maligned decision to make face recognition functionality opt-out.
"Crudely put, LinkedIn will mine your usage habits to determine what products and services you're interested in, and then use your name and photo in what amounts to an endorsement for those products and services when they're advertised to other users," he said.
"This feature is opt-out, even though it reduces your privacy and infers your goodwill, and wasn't part of LinkedIn's service when many current users signed up."
Ducklin urged LinkedIn subscribers to complain via the email@example.com email address, as well as turning off the option in question.
LinkedIn has been criticised in the past for providing cyber criminals with a treasure trove of personal information with which to launch phishing and other socially engineered attacks.
Users will now be hoping that today's news is not an indication that the site will make privacy mistakes more commonly associated with Facebook.
