The MQ2 community is a very large one. I cannot see SOE ever eradicating it. The best they can hope for is to eradicate a large portion of the active hacks.
I would go as far as to say that there is enough people with drive to hack EQ, that soe will loosen its new found crusade to fight first. It's not as simple as just hanging everyone they catch, they have to pay dearly for the rope. SOE is just pushing "the next generation" of programming and game hacks in EQ to evolve faster.
At this point, SOE can not prevent the forest from burning, The fire is everywhere and it's just a matter of tossing buckets here and there for them
