LinkedIn’s entire social fabric begins to unravel if any user can directly connect to any other user, regardless of whether or how their social or professional circles overlap. Unfortunately for LinkedIn (and its users who wish to have their email addresses kept private), this is the exact risk introduced by the company’s built-in efforts to expand the social network’s user base.

According to researchers at the Seattle, Wash.-based firm Rhino Security Labs, at the crux of the issue is LinkedIn’s penchant for making sure you’re as connected as you possibly can be. When you sign up for a new account, for example, the service asks if you’d like to check your contacts lists at other online services (such as Gmail, Yahoo, Hotmail, etc.). The service does this so that you can connect with any email contacts that are already on LinkedIn, and so that LinkedIn can send invitations to your contacts who aren’t already users.
