Broken Link Checker for WordPress
Notice: This plugin has been transferred to ManageWP. I am no longer working on it. Please direct any feedback to the new developer. See the plugin homepage for more information.
Sometimes, links get broken. A page is deleted, a subdirectory forgotten, a site moved to a different domain. Most likely many of your blog posts contain links. It is almost inevitable that over time some of them will lead to a “404 Not Found” error page. Obviously you don’t want your readers to be annoyed by clicking a link that leads nowhere. You can check the links yourself but that might be quite a task if you have a lot of posts. You could use your webserver’s stats but that only works for local links.
So I’ve made a plugin for WordPress that will check your posts (and pages), looking for broken links, and let you know if any are found.
Features
- Detects links that don’t work, missing images, deleted YouTube videos and other problems.
- Periodically checks links in posts, pages, comments, custom fields and the blogroll.
- New and modified entries are checked ASAP.
- Notifies you on the Dashboard if any problems are found.
- Lets you edit all instances of a specific link at once.
- Gives you a list of all links ever posted on your site, with the ability to search and filter it.
- Lets you apply custom CSS styles to broken and removed links.
- Highly configurable.
The broken links show up in the Tools -> Broken Links tab along. If any invalid URLs are found a notification will also show up on the Dashboard widget. To save screen real-estate, the widget can be configured to stay closed most of the time and automatically expand when broken links are detected.

Requirements
- WordPress 3.0 or later
- MySQL 4.1 or later
The current version of this plugin is only compatible with WordPress 3.0 and up. If you have an older version of WP, try one of the older releases. Specifically, version 0.8.1 is the last one that’s still compatible with the WP 2.8 branch, and version 0.4.14 is the last one compatible with WP 2.1 – 2.6.x.

Is there a wp-plugin that similarly to broken links checking allows me to check all my blogs pages for “Toxic / Spammy” outbound links – what I mean is is there something that will protect my blog from hackers that try to “Inject” spammy links inside the actual content of the posts ?

The following link, https://creativecommons.org/licenses/by-nc-sa/4.0/legalcode, is very frequently reported as broken. based presumably on a 416 return code. But the link is not at all broken. I suppose that the problem is not in the link, but in how the plugin is testing the link or interpreting the returned data.
Here is the log:
