People are going to hate, complain, flame, and harass you in any game. Toribash is no different, and a lot of times, you just need to ignore it. They're usually trying to build themselves up by tearing you down verbally.
However, when it comes to racism, take a screenshot. As you have already been told, racism is not tolerated and we will make sure that anyone using racist terminology is reprimanded.
But other than that, just ignore them. Chances are that if they can't get attention from you, they'll go try to find it somewhere else.
