Yet, it has little use for actually keeping someone from the site from coming back to post again. Worse, for reading access (especially competitors, as a simple and free workaround for that is possible, despite proxy bans).

Persistent trolls know the tricks of cookie based bans. And the ones that aren't, weren't expecting to be around for long anyway (making the hair pulling exercise of finding that "true blue" cookie based ban script worthless, as the troll made you work to keep him out -- he'll be the last one laughing).

For trolls registration moderation/private groups/forums with IP access only are the best way to keep them out. With the private route, they can't read that forum's content, either if you vett those requesters' access (something important for those who are worried about competition snooping, and having a "friend" leak content).
