It's not just you! I have a Facebook (relatively unfiltered, friends-and-comrades-only), a Twitter (kept "academic casual"), and a LinkedIn (kept really stiflingly conformist and corporate). I'm married, so I don't have to worry about dating or dating apps, but dear God, if someone wanted me to use the same persona for every social profile, I'd just shut all of them down.
Hell, I already deleted my reddit account last year just because.
