How can I make a ban appeal on that forum? DO you just get banned because a bunch of angry kids rage at you and post random pictures, not including, that the item was reserved? Is it right, to get banned out of nowhere without trial? This is ridiculous...
Ban ticket about ninja loot requires unedited screenshot of loot rules of raid from RL aswel. So no, there is trial etc, it's just that you are not involved in it. Why is it so? - Well, because raid assistants that help you recruit ppl for PUG may not include "reserved" part in their AD. It also ignores any looting rules on side resources like Discord due to how easy it may be edited.
I myself keep recording each pug raid i've joined exactly for report/apeal sake
