As an ultimate punishment, they sbould be able to post in threads, but not create their own. However, nobody else can see their posts, meaning the banned person will just think everybody ignores him.

Not really, but I would expect Bungie.next to have a more diverse set of "punishments" like temporary bans (hours, minutes, seconds) bans from creating threads, but not posting in existing threads, specific forum bans, ect. Some might not be used much but having more options opens the door for better ways of dealing with trouble makers or even first time offenders.
