Sometimes you may want to limit who can interact with you on the platform.
If you encounter someone you don't want to interact with on Noice, you can block them from seeing your profile, seeing you're online, seeing you on chat or leaderboard, or being on the same team or party as you. You can do this wherever you see their username -- click on their username or profile icon, and select "Block User".
Other users will not be notified that you've blocked them, but be aware they may guess you have when they can no longer visit your profile.
You will also not be able to see any users you've blocked in chat or leaderboard.
You can unblock users you previously blocked by visiting User Settings -> Privacy and clicking on "Show Blocked Users".
