It can also help if you’re manually trying to ban someone and their name is something like IlIlIlIlIlIlIlIlIl or X3834Sjkewj. Or even if someone tries to trick you by naming themselves allAbcido3 or otherskjsdf.
All you need to read is IlIlIlIlIlIlIlIlIl [432] which you can use to find them easily without having to try to type their username. Difference between this and Roblox userIds are that Roblox UserIds look like this: 1370939403 which just makes it impossible to remember.
