problem with user promotions

[geezzaa]

Hi all i wonder if someone would kindly help me out.
I have a hidden sub forum for users who achieve 500 post, however i cannot ban anyone from that forum, if i untick the box in the users permissions the system puts it back in an hour later when it updates
could somebody please tell me how to get round that
Cheers
