It is the replacement for Free Market stores after all, which had transparency in who you were transacting with.
You seem to be under the impression that bots didn't make use of those as well. Simple enough matter to transfer things to a more "legit-sounding" character name and then sell them like that. I'll give you, though, that it's become far more blatant with the auction house.
Honestly, when i made this idea, i was being half joking and half serious. On one hand, some of this stuff is absolutely absurd, but on the other hand, philo books and marvel machine have a lot of junk still mixed in nexon needs to clean out (ex. fafnir weapons). i would definitely like to see the reward pools for marvel / philo slimmed down a bit and more junk removed.
