This is clickbait and does not belong on the front page of HN. The author says he scraped public profile URLs and names. When you make your profile on social websites public, then you have chosen to...make them public. He then claims he has emails from LinkedIn, but those emails are from an old data breach, and he even admits that the emails are limited to those found in a 2012 data breach. Finally, the title of this article says he did this for “fun and profit”. By the author’s own admission, the “profit” part is missing here. He claims the company “...went out of business without getting funding”. So in other words, he has access to the main LinkedIn website, found a link to a database from an old data breach, and used to work for a now defunct company. None of that translates to “Harvesting LinkedIn data for fun and profit”.
