Its a play on the 'The Spy Who ___ Me' title meme. I thought it was very fun and did a good job communicating how mundane the lives of the spies really were, which appeared to be a thesis or at least supporting point of the article.
Tl;dr: Russian spy brought bug into secure facility, revealed other spies. FBI deals with it.
Not sure why LinkedIn is even mentioned... a quick search on the whole page (ignoring the title/post categories) is just this one sentence...
> By day, Buryakov lived the ordinary life of a Wall Street analyst: reading and writing reports; attending meetings, conferences, and parties; building connections on LinkedIn.
But its an interesting read, even with the weird title...
That I was able to work out the intention of a sentence does not mean the sentence should have existed in the first place. It's already used up more of my time than any actual content—why didn't they use a descriptive title?
Nothing to do with LinkedIn as far as I can see.
