Allows for whitelisted URLs to not count against the comment moderation max number of links limit.
On the ‘Settings’ -> ‘Discussion’ admin page, WordPress allows admins to define the maximum number of links permitted in a comment before that number of links automatically triggers moderation for a comment. That setting is labeled “Hold a comment in the queue if it contains N or more links” under “Comment Moderation”, where “N” is the input for the specified number. If set, WordPress will blindly count any link that appears in the comment and hold that comment for moderation if enough links are found.
In certain cases, however, you’d like to your visitors to be able to link to certain trusted URLs (such as your own site) without it counting towards the moderation link count limit. Unnecessary moderation of comments that simply contain links to resources you trust puts additional burden on comment moderators and hampers discussions.
Simply install this plugin and specify a list of trusted domains, and then links to those URLs will no longer count against your commenters.
Note: It is unnecessary to specify the protocol when listing URLs. Also, subdomains are inferred and need not be explicitly listed.
