The reason clans do this is because a majority of the seasoned players in these clans have determined that some set of boundaries need to exist, even in their virtual world. People in the real world aren't allowed to just run around doing whatever they want. Whether a world is real or virtual doesn't change the concept. There's nothing wrong with expecting people to display some manners and common courtesy. If they fail to, then those clans simply exercise their right to refuse to play with that person. Are you saying that the rude player has all the rights but the clans have no right to their own code of conduct?+1 you think this is bad? You should go see taranis's topics lmao, their top clans pretty much enforce rules that they expect everyone to follow xD but that's something to be discussed here.
I agree that any player has the right to KS a lix or be a rude, immature idiot. I will grant you that this is their right. By the same token, clans have the right to refuse them membership. Eventually, they will get tired of killing the dog in lirs reach and quit.
