I notice often when someone who isn't entirely or not associated with an appeal or report put a genuine non trolling comment that defends or is a counter argument to the report/appeal and then to have their post hidden by staff for no apparent reason, now I am aware that staff can see these hidden posts but what is the reason for hiding them from non staff, it cant be for "cluttering" the post since staff (the people who truly decide) can still see it, and it cant be for being a "useless comment" that adds nothing because it usually has enough detail to explain their point. I don't mind the random comment of like 6 words just insulting the poster or the one who got reported being hidden/deleted but what I don't understand why player opinions are hidden from other players. Is there a reason for it?
