You can usually hide usernames in JJS custom/private servers by editing the server’s player visibility or team settings, not by turning off names globally. A recent JJS private-server page notes the owner has a menu with several commands, and related community posts/videos point to “display name” or leaderboard visibility controls as the place to change this.

What to try

  1. Open the private server owner menu.
  2. Look for options related to:
    • player list,
    • name tags,
    • display names,
    • leaderboard visibility,
    • stealth/anonymous mode.
  3. If the server uses teams, place players on a neutral or hidden team so they don’t show up the same way on the board. Community examples for JJS describe using team/block setups to make a player disappear from the leaderboard while still staying in the server.
  1. If your goal is only to hide your own username, check whether the client has a privacy or display-name toggle. In some games, the server can only hide the player sample, not fully remove all in-world tags.

Important limit

There may not be a true “turn off usernames” switch in every JJS custom server. A lot depends on how the server owner set it up, and some methods only hide you from the leaderboard or player sample rather than removing name tags completely.

Practical wording

If you’re asking the server owner, a useful request is: “Can you enable hidden name tags / anonymous mode / team-only visibility for this custom server?” That matches the kinds of controls people are using in current JJS private- server discussions and tutorials.

If you want, I can turn this into a short step-by-step post you can paste into a forum or Discord.
