Just as the author has greatly explained the "MOD'" is on a ego trip. Allowing non paying members the benefit of doubt when disagreements happen, which is all the time. Other members try your patients and when called out turn and cry foul to the "MOD" then the "MOD" take the said of the cry baby's and restricts the other user from posting from one day to as much as five days.
Freedom of Speech does not exists there at all and trying to enforce the First Amendment is useless and pointless. I think that would be discrimination but who to you complain about that too?
