I'll clarify it again just for you, because you are slow: Our Polish regulars agreed with our banning of their retarded fellow Poles. Funny how you bring up this very, very old thing though. You even made me think about what countries we have banned. Look
here for a complete list of banned zones.
How you think you can understand the reasoning behind our banning practices, while you have no idea what our banning practices are, is quite amusing, but if you really want to think you do understand, then I will not shatter your dream.
If the playerbase of a server is made up of lamers, that means the admins of the server suck, unless they want their server to be populated with lamers, in which case they are doing a great job. Assuming they want nice players on their server, the admins are there to make sure that the playerbase is made up of nice players, and not lamers. If you criticize the playerbase, you directly criticize the admins, since they are responsible for the playerbase. They decide who comes in and who is forcefully let out the backdoor. Maybe you should not spend your time on servers that are full of camping/tking lamers, because it quite clearly is obscuring your view on the rest of the public servers out there. Sadly, I don't really know any good, populated American public servers, but I'm fairly certain someone can help you out with this.
And last but certainly not least, please don't fool anyone into thinking the games on your clan servers are any different from the games on public servers. The only noticeable difference is probably that clan servers have a much higher density of retarded people than the average public server.
