I had the good sense to use a fake name long ago when I first signed up for facebook. A handful of my friends did the same. Over the years it has paid off in terms of people I don't know not being able to look me up. I'm also lucky to have a very common name. I am very un-googlable unless you know actual details about my professional life, in which case you can learn a bit more about what I do for work, but nothing else.
I also have a secondary facebook account with my real name whose "friends" are only random acquaintances who have bothered trying to connect with me over the years. I have used this in the past when potential employers, or border guards, have asked about my online presence.
I've been online since I was young and deep dark secrets about me are contained and findable on old forum databases and fragments of lost proto-social networks. I might be over-confident, but I'm almost sure not even palantir knows.
All our accounts will eventually be linked by our writing style.
I love having a really common name. Growing up, my neighbor down the road had the same name and we'd get each other mail sometimes. One time I even met a guy who had the same middle name as me. It's kind of funny, my name is so common you can't find me on Google, and my girlfriend's name is so unique that there's almost 100% certainty that nobody else in the world has her name, so very googleable. I love the anonymity of my common name and she loves the unique identifier that is hers.
