I asked a related question about how often you lie, on a daily basis, but I think this is more apropos for today’s general aesthetic.
Thinking about it, I definitely misrepresent myself online 100% of the time, as I never say who I am. I do say a lot of things, but in a generic sense, enough that it would be hard to pin down who I actually am. I have a deep and irrepressible sense of distrust for the state, for decades, despite what I do for a job. So instead, I have an online persona that does indeed reflect my values, but is separate from the public facing person you might know.
Unless you’re limiting yourself to very terse responses or having someone else (ideally random) write all your online content, you’re still very much at risk.
Ed, I told you to get of the internet and turn off the light, I’m tired. And if you steal the covers again tonight you are sleeping on the couch for a week. Did you remember to take the trash out? Don’t sigh at me… you know how I hate that. Goodnight Ed.
