Do you think some people might be either addicted to, or morbidly obsessed with, BV? I couldn't really say for sure but the behavior of people like ninor/rath indicates that the answer is a yes.
Now that that is established...why ?
I believe that it's an energy exchange "Hub" where many come to dole out their thought for food and many others come to ravenously feed from the energy so generously given. Keep in mind that serving and consuming the served are not really bad things; it happens just about everywhere you look in nature.
The energies form a confluence, somewhat like a super-consciousness. A convergence and a divergence. Contraction and expansion. This is why it's important to clean house. Now one might ask "should at1 have been banned over this" and my only defense is that I was the one shooing with my broom, not the dirt being swept.
