Social media presence as in having accounts in your name with you being visible in the profile picture in mainstream sites (Anything Meta, Twitter, Snapchat, Tiktok…). I don’t consider anynounmous accounts on Lemmy, Reddit, Kbin relevant to the scope of this question.
Well, anecdotally I have no mainstream social media, and also no real friends where I live. But that might also be the Persistent Dysphoric Disorder’s fault. Also, people suck and I’m fine spending most of my time with my wife.
