Banned for mining, is it permanent?

Hey, when I was away for about and hour and a half I got banned for "Thorium filon exploit in Silithus". Apparently GMs ban without even warning about the thing your doing is an exploit. Apparently mining in Silithus is an exploit.
Anyway, read about some other guys' ban notice on the site says "expires on" etc etc and that it was because it was permanent. Cause it has gone a couple of hours past said time.
Ban notice:
Will this be lifted or is this shit permanent?
