LinkedIn violated data protection by using 18M email addresses of non-members
I'm constantly alarmed by the recommended matches on LinkedIn. I'm also torn by the business community's insistence that this site is a necessary part of networking and any of its practices are therefore beyond scrutiny.<p>And no, you did not match me to my second cousin "based on my profile." Unless you mean "based on your email address, which is already included in the massive social graph of all address book connections we've harvested from people who know you."<p>If you have to mislead your users about how you're finding potential connections, maybe you shouldn't be doing that thing in the background, or maybe you shouldn't be so focused on aggressively pushing those connections.
