You install these software modifications at your own risk. If it compromises your client so that it no longer works as intended or your account ends up compromised then its on you. If it sends questionable data packets into the game server resulting in a ban then that's also on you. You agreed on installation to use the service per the terms given and chose not to uphold your part in that agreement.
