Auto-moderate comments on old WordPress posts
You know those really annoying three ancient posts on your blog that the spammers hit over and over for whatever reason? This plugin lets you set all posts over a certain age (as defined by the last time any approved comments were posted) to have their comments moderated – or shut down. You can decide how many days old a post thread should be before this happens, configure it differently for “popular” posts, defined by how many comments they’ve had approved (again, you set this number).
I’ve set this up on two sites that keep getting hit.
