shows how deep I was into the idea of having a unified online persona I will never understand this outlook. Why would I use the same name on more than one website? Why would I ever do anything online under my real name? I suppose it would be a benefit if you were trying to get famous and make a living off being an influencer but otherwise it's incomprehensible to me.
