Good Idea: Leaving Off-Topic mostly unmoderated, as it has been successfully for quite a while.

Bad Idea: Having a sudden change of heart and moderating the hell out of it.

Good Idea: Rethinking the ridiculous sudden spike in moderation and unlocking the half a page of locked threads.

Bad Idea: Advertising to the entire internet that OT.com's Off-Topic section is now officially unmoderated with the words "(unmoderated)" next to it, effectively inviting everyone and their brother to drop by and cause as much trouble as possible.
