There's this retardedly simple concept of blocking the ads, considering it will be an ad server delivering them.
There are two big potential problems with this. First on a technical level, how is the game going to react to this blocking? You do realize that it could be written to refuse online play if the ad and tracking servers are unreachable especially when the master list server still is. Or network performance could be noticeably affect as the game repeatedly retries to send and receive the ad information to/from the blocked hosts. Second, there is the legal issue. Blocking the ads and tracking could be made a violation of the EULA which could result in a ban of the game's CD key/account.
Blocking the ads is no more a viable solution to the problem than not buying the game and downloading a hacked copy of the game.
