I couldn't tell you if this was a hack or not without experiencing the problem. However, each time a patch is released all hacks are removed for quite some time or until some of the utility companies out their builds a new hack.
I know that their is allot of work being done in both the private and public sectors to stop this sort of game play and I wish that those people using these sort of utilities would understand that they are ruining a fun time for more then 1 player.
As for UGC it's not tolerated if proof of the the act can be provided. Screen-shots, Screen-shots my friends.
