This is a... I dont know really. You change the name of your server so you can hack and not worry about getting in trouble with other players, getting hell from the person you hacked, or not worry about someone attcking one of your other servers. At first it was all low level attacks, so there was not much lost. But now peopel are more powerful and can do a lot more damage faster, so theres a lot lost.
And you cant do a thing about it cause; 1-You dont know who did it, 2-The sever it self is alwas changing IPs, 3-Even if you hack it, most of the programs are some what different from there others so you cant compare to someone else. 4-Even if you hack them and delete there hacking tools, they ussauly have backup on their Gold FTP.
And it ruins something that we do with others; 1-You cant warn people about these players, 2-You and your friend cant trace him/her (but i dont think many girls play) and 'explain' to him what he is doing WILL get you into trouble, 3-You dont know if this person is one of your best friends in the game.
I have 5 servers, 4 of them have my user name in the title, the other one is called a random word, so if I get hacked on all my servers I still have that one that the wouldn't be known as mine.
Changing name is more for organizational I think. It helps you keep track of serveral servers you have without having to memorize which is which.
Thats what changing the servers name should be used for.
