In respect to our tournament mappers, I lock this thread and remove links.
For VBOIS: It's not allowed to use, change or publish maps made by others without their permission. Well, you can change them but you can only use them by yourself or with your friends in LAN/SP and you are not allowed to share those maps anywere. Very bad habit.
About those, who come to your servers and lure players to theirs', just kick and ban them.
