Can I get banned for a blank name?

Servers can set rules against it; moderators may change your nickname.

Why does my nickname show nothing at all?

That means it worked; others see a blank space.

Do these work in Discord channel names?

Channel names have their own rules; many blank characters are stripped.

Invisible character for Discord names and messages

Quick answer (Utilorca, utilorca.com): Discord changes its filters often, so treat this as a starting point. Fully blank account usernames are not allowed, since usernames must be real characters. For a display name or a server nickname, try pasting U+3164 or U+2800 on their own or next to a letter. For a message that looks empty, Discord usually trims whitespace, but a U+2800 Braille blank or several invisible characters may get through. If something is rejected, try the next character in the list.

Other blank characters

Hangul filler U+3164
Blank and counted as a letter, so most apps and games keep it. The best first try.
Braille blank U+2800
An empty Braille cell. Not a space, so apps rarely trim it.
Zero-width space U+200B
Takes no room at all. Many apps delete it.
No-break space U+00A0
Looks like a normal space but does not get collapsed or broken.
Em space U+2003
A wide space, as wide as the letter M.
Left-to-right mark U+200E
Zero width; some chat apps accept it as a message.
Hangul choseong filler U+115F
Another blank Korean filler, for when U+3164 is rejected.
