If you're an adult on the internet in 2015, chances are you get bombarded with emails inviting you to join someone's 'professional network' on LinkedIn hundreds of times a day.

The old days of constant penis enlargement spam and messages from deposed Nigerian princes may be over, but LinkedIn emails continue to clog up our inboxes.

And as more and more of Hillary Clinton's private emails are released amidst ongoing controversy over the issues of a high-ranking politician using a private email server instead of a government one, it's become clear that even the former secretary of state isn't immune from LinkedIn invitations.

Among the latest tranche of emails released by the New York Times is a series of messages spotted by Business Insider showing Clinton's confused reaction to an unsolicited LinkedIn email.

Clinton was invited to connect by a woman called Susan Kennedy, former chief of staff for Arnold Schwarzenegger when he was governor of California.

In an email to two aides, Clinton simply wrote: "How does this work?"

The aides, Robert V Russo and Monica Hanley responded, explaining the mind-numbing concept of LinkedIn to their boss.

This particular handful of emails isn't of the same national importance as some others that have recently been released, but it's refreshing to see that even those at the top of most powerful nation in the world are just as bemused by LinkedIn as the rest of us.

The emails were sent in February 2012, and obviously Clinton has now got the hang of LinkedIn - describing herself as a "hair icon" and "pantsuit aficionado" in her bio, she's amassed over 100,000 followers and gained a coveted 'Influencer' title since joining.
