Can't access previous username

Hello there,

After several years of successfully posting on these forums with my previous username of "scotty321", I was apparently given an infraction for posting something that was against the forum's terms of conditions. I'm GUESSING that this is what happened, because I was never alerted to an infraction, but suddenly my username no longer had any privileges on the forums anymore, including reading private messages. I no longer had permission to read my 1 new incoming private message (which I assume was trying to tell me that I received an infraction??), I could no longer reply to any message threads, I could no longer edit my profile details, I could no longer start a new post, nothing. So to this day, I still have no idea what I did wrong or what I can do to "release" my old username from purgatory. I sent MULTIPLE emails to the support staff (outside of the forums... just using a normal email client) and nobody ever got back to me. Can somebody please explain to me what happened, why my entire account was shut down, and what I can do to "release" my old username from purgatory? It doesn't make sense that I had to create a completely brand new username just to try to find out what happened to my old username, and that nobody even responded to my emails. 

Thanks,

Scott
