To stop Discord from showing Roblox, open Discord, go to User Settings , then Activity Privacy , and turn off “Share your detected activities with others.” That hides the game/status display on your profile.

If Roblox still shows up

You can also check Registered Games or Game Activity and disable Roblox specifically there, or turn off the Discord overlay for Roblox if that’s what you’re seeing.

Quick steps

  1. Open Discord.
  2. Click the gear icon near your username.
  3. Go to Activity Privacy.
  4. Turn off Share your detected activities with others.
  5. If needed, go to Registered Games and hide Roblox there too.

Mobile note

Some sources note that these game-activity controls are easier to manage on desktop, not mobile.

TL;DR

Turn off Activity Privacy in Discord, and if Roblox still appears, disable Roblox under Registered Games or turn off the overlay.
