You have the power to exclude yourself from the 'Find a Player' search feature.
If someone is bothering you in chat, you can always use the 'Block Chat' option. To do this, right-click on the player's image and select 'Block Chat'. At the moment, it's unavailable on mobile devices.
Some players are just trying to get a reaction from you. We recommend ignoring them or blocking their chat so you can enjoy the rest of your game.
