If a player is bothering you or just simply blocking your view in-game, you can put that player on your ignore list. You can do this by clicking on a player, so that the player’s icon will pop up on the top of your screen. Click on the icon and choose Ignore from the bottom of the list. The player will disappear and won’t be able to talk to you anymore.
If you want to remove that player from your ignore list again, either press the F-key or the friends icon in the Horseshoe Menu and click on the Ignore tab. Click on the respective player you want to remove and choose Delete. The player will now be visible again.
You can also add players to this list by entering the player name (make sure it’s spelled correctly!) at the bottom of that window and choosing Add.
Click on the Ignore tab to add players.
