F - Account closure / permanent ban : Most serious sanction. Permanent ban are rare but definitive.
Examples :
Possession of an item(s) obtained with illegal methods
Advertising for other private servers,
Creation of another account to bypass a sanction applied on the first one (except for permanent ban),
Publishing a software, methods or articles on cheating which can be applied on the server,
Revealing the identity of a Nostalrius Begins staff member,
Selling/Buying an account, golds, services or items for real money,
Account hacking,
Client's modification (libraries, executables, MPQ, etc.),
Any attempt to bribe a staff member to gain an in-game advantage,
Organized killing for farming rank and/or honor,
Multi-account which strikes a blow to players,
Abuse of in-game bugs,
Using bots.
Hacking.
So, "Organized killing for farming rank and/or honor" consider as a most serious sanction and it will be punished with Account closure / permanent ban.
So, all the players that exploits the roofs of Tanaris or the mast Boody Bay or waiting at flight points to kill enemy players aren't orginize killings for farming honor and rank? Maybe its time to start applying those rules?
From what I seen this thing happens constantly by the same players. I am an ally and all the time I see the same horde players doing this organized farming (I can name them but this post isn't about names right now). I am sure players from ally side doing the same. And guess what: those massive exploit honor farming gives them easy honor and faster ranks.
OK, this is a pvp server but also has rules. Isn't the time to start applying them?
