The reason we don't allow people to discuss bans here is because this is an unofficial forum, there is nothing we can do to get you unbanned.
We also only get one side of the story, most bans given out are for a good reason and most posts about bans on these forums are just guilty people lying in hopes it'll help them out which it won't.
My tickets have always been answered in a day or two so I'm not sure why ban support tickets often don't get replied to but my guess would be if they feel you deserve to be banned they just don't reply and only reply to let you know it's going to be overturned if they choose to do so.
