AOMH - that was in the update notes (the "see ncu of all players" - not a direct mention of the hack, but everyone knows what was being discussed)
MB - that was in a thread when the complaints started about it's use, the reasons explained about the ability for FC to be able to detect MBing vs Multi-logging by a FC current and FC past employee (iirc).
DM - in the thread a week or so ago when the video was put up of it being done at towers. Genele responded to a PM from a player and the player posted the response. The threads were then all deleted (not closed, completely deleted). I am sure copies of that post are still around.
That's kinda why I used those 3 examples - since they were complaints from both sides, recent issues, are 3 different game mechanic issues/problems and all had some sort of FC response.
