We reserve the right to review cases involving exploits on an individual basis and take action as deemed necessary. For minor offenses a formal warning is issued, another warning or a more serious offense will get a temporary ban from the game and for very serious violations or repeated offenses the user can be banned permanently. We reserve the right in all cases to deem the seriousness of offenses. We also reserve the right to delete characters and/or items that were gained through the use of exploits. Note that any attempts at hacking the game or servers will be dealt with very severely, even with lawsuits.
