When you ever play anyone within the game and they have red rank in casual or they taunt at you after they kill you. They are not a nice person at all. So what you should do is to leves the sever to make sure that the person who is not nice is not having fun. This goes for any sever. Not just causal. ANY sever you go into and if there is a good player you should level because most likely they have a big ego and they will bully you because they are better. And if they are not even saying anything they will be mean and bully you by keep killing you. I will say not to try to get an admin due to once the admin will get in. They will stop but then will continue once the admin leves. This has happened to me many of times. Not just one tf2maps sever but on other maps.
