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? <a href="https://webberzone.com/plugins/autoclose/" rel="nofollow ugc">Auto-Close Comments, Pingbacks and Trackbacks</a> lets you automatically close comments, pingbacks and trackbacks on your posts, pages and custom post types.
You can also choose to keep comments, pingbacks, or trackbacks open on certain posts, pages or custom post types. Just enter a comma-separated list of post IDs in the Settings page.
An extra feature is the ability to delete post revisions or limit their number.
