My hot take on the discord username rollout is there was never a functional difference between shel4378 and shel#4378 or between @markiplier and markiplier#0000
Like the usernames were always "unique" they've been unique the whole time. There's no reason not to just choose your existing username and tack on your existing discriminator if you want to be impossible to find. The argument that it "makes datamining easier" makes no sense. Every account already has a unique ID in the database you wouldn't use someone's handle for datamining. The user facing side is obviously not the backend or else when you change your handle it would fuck up all the servers you're in.
And if you're concerned about new accounts like ok forcing people to use 4 random numbers is a way to force good OpSec but otherwise just don't choose the same username everywhere if you're concerned about Being Found. My telegram handle is not @workingdog and I didn't choose that for my discord either.
I guess username squatting and reselling is... An issue? But it doesn't really affect anyone in a way that matters. Who cares if someone squats @markiplier and he pays to get it. Or Discord can just force change @markiplier to @markiplier_ and give the original handle to the famous guy like every social media website does. Plus people already could do this with nitro if they chose markiplier#0000
