I have been studying and practicing the occult for about ten years.
I am not going to argue back and forth with people on this; I will simply state my policies: I do accept anything occult from another person that I don't know, I don't buy any used occult items whatsoever, and if I am buying some mundane item secondhand, if I see ANY occult symbolism on it, I will not buy it.
So far, so good.
