Description
Spammers target old posts in a hope that you won’t notice the comments on them. Why not stop them in their tracks by just shutting off comments and pingbacks? Auto-Close Comments, Pingbacks and Trackbacks let’s you automatically close comments, pingbacks and trackbacks on your posts, pages and custom post types.
You can also choose to keep comments / pingbacks / trackbacks open on certain posts, page or custom post types. Just enter a comma-separated list of post IDs in the Settings page.
An extra feature is the ability delete post revisions or limit their number.
