I'm a boomer and I never used discord except to go to a guild channel for an online game like hello kitty island adventure. If I start going to other discords where I might start participating more professionally, are they all going to see my history as a hello kitty island adventure guildie or can I undo that somehow? I heard they are all linked together for some reason. Also I saw some news headline where discord was exposing some private stuff of its users. Should I be afraid of it? I'm from the days before anyone was supposed to give any personal information to the internet.
