Hexometer has developed a Broken Links Repair Plugin, which disables your content broken links upon detection. You can enjoy this tool from now, just install the plugin and connect with your website monitored by Hexometer (you can find the verification code in the property settings page at dash.hexometer.com). The plugin will automatically disable detected broken links from your WordPress content until you will fix or change them manually.

It is important to understand that the 404 links (broken links in other words) are being disabled by the plugin but not fixed permanently, and you have to fix them anyways. Also, there are cases when the links will not be disabled due to other plugins installed or firewall settings.
