Kitty, you were warned for using the r-word because slurs fall under the hate speech rule. What slorp said here was not attacking you based on your personal circumstance, or using other's personal circumstance to attack you. If these comments bother you, In the context of this game I suggest possibly reviewing over the harassment rule.
