I'm sorry when was this established? Or when did the op get proven as a liar? I've seen plenty of people claiming he must be because THEY don't do this so it must never happen, and that ACT is God's gift to raiders so he must be crazy.
I still honestly believe most of what the op posted however as I've seen this behavior aimed at sprouts and players in learming dungeons as well. If it did not happen to him, it's happening to other players and his points still stand.
