Yes, everytime I join a game in Demoltion, a hacker or modder is in EVERY lobby. Nintendo or Activision really does nothing about it. People are saying you can "report" there gamer tag to Activision, but I have doubts about that.  Even if they DOD read them, they probaly wouldn't take action. Atleast made an update, where you could send Support team, or Moderators, or someone within Activision or Nintendo to have a banning tool. For now, It's remaining a mode where hackers go code happy all over the place.
