[2020] How to stop showing players online?

Hi @AlineAndreato, welcome to the community.

If you own a private server, you can change that setting by logging into the G-Portal app and setting the VocalVisibilityDurationInMinutes parameter within the Basic Settings to any number other than 0 to enable hiding player names in the server list, which will be the duration in minutes by which a player will be listed in the player list after participating in chat.

If you set that value to 0, this feature will be disabled.
