The rules specifically state that discussion bans within game or the forums isn't allowed and it should be taken up to one of the Staff members (Maybe the one that banned you).
Rules (http://www.feral-heart.com/index.php?option=com_jfusion&Itemid=2&jfile=index.php&topic=18317.0)
"Discussion Of Bans And Reports
Discussions about bans and reports should NOT take place inside the game, except closed conversations. If you end up getting warned, kicked, or even banned from the game, you do not under any circumstances discuss this in the public chats or complain/seek attention. If you are unhappy with a Mod's actions or warnings within the game, or possibly a member breaking the rules, you should contact the Administrators or Mods here on the site and explain your situation via a PM form. If it's seen as necessary, a MOD within the game might warn/kick/ban a user for trash talking, bad mouthing, or being disrespectful toward the rules that were enforced on them from recent events. Warnings, kicks and bans are given for a reason!"
