Hello and welcome to osu!!
I don't think people can find your Discord by knowing your osu! name, even if it's linked. If you'd like you could add agu#1982 on Discord, I promise not to bite.
I might edit away the Discord link if I get a bunch of friend requests after this somehow but I don't think many people check the introductions forum, I'm just kinda bored so I decided to give you the honor of being welcomed by me, enjoy your stay!
